Jodi Arias' Friends Believe in Her Innocence

Accused murderer Jodi Arias believes she should be punished, but hopes she will not be sentenced to death, two of her closest friends told ABC News in an exclusive interview.

Ann Campbell and Donavan Bering have been a constant presence for Arias wth at least one of them sitting in the Phoenix, Ariz., courtroom along with Arias' family for almost every day of her murder trial. They befriended Arias after she first arrived in jail and believe in her innocence.

Arias admits killing her ex-boyfriend Travis Alexander and lying for nearly two years about it, but insists she killed Alexander in self defense. She could face the death penalty if convicted of murder.

Nevertheless, she is aware of the seriousness of her lies and deceitful behavior.

The women told ABC News that they understand that Arias needs to be punished and Arias understands that too.

"She does know that, you know, she does need to pay for the crime," Campbell said. "But I don't want her to die, and I know that she has so much to give back."

The lies that Arias admits she told to police and her family have been devastating to her, Bering said.

""She said to me, 'I wish I didn't have to have lied. That destroyed me,'" Donovan said earlier this week. "Because now when it's so important for her to be believed, she has that doubt. But as she told me on the phone yesterday, she goes, 'I have nothing to lose.' So all she can do is go out there and tell the truth."

During Arias' nine days on the stand she has described in detail the oral, anal and phone sex that she and Alexander allegedly engaged in, despite being Mormons and trying to practice chastity. She also spelled out in excruciating detail what she claimed was Alexander's growing demands for sex, loyalty and subservience along with an increasingly violent temper.

Besides her two friends, Arias' mother and sometimes her father have been sitting in the front row of the courtroom during the testimony. It's been humiliating, Bering said.

"She's horrified. There's not one ounce of her life that's not out there, that's not open to the public. She's ashamed," she said.

French, Malian forces fight Islamist rebels in Gao

GAO, Mali (Reuters) - French and Malian troops fought Islamists on the streets of Gao and a car bomb exploded in Kidal on Thursday, as fighting showed little sign of abating weeks before France plans to start withdrawing some forces.

Reuters reporters in Gao in the country's desert north said French and Malian forces fired at the mayor's office with heavy machineguns after Islamists were reported to have infiltrated the Niger River town during a night of explosions and gunfire.

French Defense Minister Jean-Yves Le Drian told a news conference in Brussels that Gao was back under control after clashes earlier in the day.

"Malian troops supported by French soldiers killed five jihadists and the situation is back to normal," he said.

In Kidal, a remote far north town where the French are hunting Islamists, residents said a car bomb killed two. A French defense ministry source reported no French casualties.

French troops dispatched to root out rebels with links to al Qaeda swiftly retook northern towns last month. But they now risk being bogged down in a guerrilla conflict as they try to help Mali's weak army counter bombings and raids.

"There was an infiltration by Islamists overnight and there is shooting all over the place," Sadou Harouna Diallo, Gao's mayor, told Reuters by telephone earlier in the day, saying he was not in his office at the time.

Gao is a French hub for operations in the Kidal region, about 300 km (190 miles) northeast, where many Islamist leaders are thought to have retreated and foreign hostages may be held.

"They are black and two were disguised as women," a Malian soldier in Gao who gave his name only as Sergeant Assak told Reuters during a pause in heavy gunfire around Independence Square.

Six Malian military pickups were deployed in the square and opened fire on the mayor's office with the heavy machineguns. Two injured soldiers were taken away in an ambulance.

French troops in armored vehicles later joined the battle as it spilled out into the warren of sandy streets, where, two weeks ago, they also fought for hours against Islamists who had infiltrated the town via the nearby river.

Helicopters clattered over the mayor's office, while a nearby local government office and petrol station was on fire.

A Gao resident said he heard an explosion and then saw a Malian military vehicle on fire in a nearby street.

Paris has said it plans to start withdrawing some of its 4,000 troops from Mali next month. But rebels have fought back against Mali's weak and divided army, and African forces due to take over the French role are not yet in place.

Islamists abandoned the main towns they held but French and Malian forces have said there are pockets of Islamist resistance across the north, which is about the size of France.

CAR BOMB

Residents reported a bomb in the east of Kidal on Thursday.

"It was a car bomb that exploded in a garage," said one resident who went to the scene but asked not to be named.

"The driver and another man were killed. Two other people were injured," he added.

A French defense ministry official confirmed there had been a car bomb but said it did not appear that French troops, based at the town's airport, had been targeted.

Earlier this week, a French soldier was killed in heavy fighting north of Kidal, where French and Chadian troops are hunting Islamists in the Adrar des Ifoghas mountains, which border Algeria.

Operations there are further complicated by the presence of separatist Tuareg rebels, whose rebellion triggered the fighting in northern Mali last year but were sidelined by the better-armed Islamists.

Having dispatched its forces to prevent an Islamist advance south in January, Paris is eager not to become bogged down in a long-term conflict in Mali. But their Malian and African allies have urged French troops not to pull out too soon.

Singapore trade expands 1.1% in 2012

SINGAPORE: Singapore's total external trade rose by 1.1 per cent in 2012, a contrast to the 8.0 per cent rise seen in the previous year.

The trade growth is lower than the previously projected range of between 3.0 and 4.0 per cent, said IE Singapore in its news release on Friday.

This, IE Singapore said, is due to poor trade performance in 4Q 2012.

Total trade reached S$984.9 billion in 2012, higher than the previous year's achievement of S$974.4 billion.

On a year-on-year basis, Singapore's total trade dropped by 2.9 per cent in 4Q 2012, following the previous quarter's decrease of 2.2 per cent due to decreases in both oil and non-oil trade.

Non-oil domestic exports (NODX) rose by 0.5 per cent in 2012, following the preceding year's increase of 2.2 per cent, due to higher shipments of non-electronic exports.

IE Singapore said the 0.5 per cent growth is lower than their projected 2012 growth of 2.0 to 3.0 per cent. This is due to a worse than expected NODX's performance in 4Q 2012.

Looking ahead, IE Singapore said projected total trade for 2013 is maintained at between 3.0 and 5.0 per cent while projected NODX growth for 2013 is kept at between 2.0 and 4.0 per cent.

British intel had warned of Indian Mujahideen attack

NEW DELHI: The British intelligence had warned India about a possible terrorist attack by the homegrown terror outfit, Indian Mujahideen (IM). The alert led to a general nationwide alert on Wednesday.

The British intelligence alert is believed to have been received by Indian agencies just as British PM David Cameron was about to land in Mumbai on Monday. The input did not speak of any specific movements of terrorists or any particular module. Sources said it may have been based on inputs gathered by the heightened British intelligence gathering in the region ahead of Cameron's visit.

On Wednesday, a general alert was issued by the Intelligence Bureau (IB) about a possible attack by the IM. The alert was based on the British input, and came after several weeks of silence about any IM activity.

There are no dependable inputs with agencies until now about any IM module being active of late, sources said. However, investigations of recent times have indicated that the entire network of the homegrown terror group may not have been unearthed.

The IM tentacles are not just limited to some Indian cities, but it also has very strong affiliations among the Indian diaspora. The activities of IM are believed to have regular funding from West Asian countries. Also, some of the first Indian terrorists to have emerged in the communally vicious times of the 1990s — mostly having undergone terror training in Pakistan — are now based in the Gulf region. Among them is C A M Basheer, a former senior SIMI leader.

Flu shot doing poor job of protecting older people

ATLANTA (AP) — It turns out this year's flu shot is doing a startlingly dismal job of protecting older people, the most vulnerable age group.

The vaccine is proving only 9 percent effective in those 65 and older against the harsh strain of the flu that is predominant this season, the Centers for Disease Control and Prevention said Thursday.

Health officials are baffled as to why this is so. But the findings help explain why so many older people have been hospitalized with the flu this year.

Despite the findings, the CDC stood by its recommendation that everyone over 6 months get flu shots, the elderly included, because some protection is better than none, and because those who are vaccinated and still get sick may suffer less severe symptoms.

"Year in and year out, the vaccine is the best protection we have," said CDC flu expert Dr. Joseph Bresee.

Overall, across the age groups studied, the vaccine's effectiveness was found to be a moderate 56 percent, which means those who got a shot have a 56 percent lower chance of winding up at the doctor with the flu. That is somewhat worse than what has been seen in other years.

For those 65 and older, the vaccine was only 27 percent effective against the three strains it is designed to protect against, the worst level in about a decade. It did a particularly poor job against the tough strain that is causing more than three-quarters of the illnesses this year.

It is well known that flu vaccine tends to protect younger people better than older ones. Elderly people have weaker immune systems that don't respond as well to flu shots, and they are more vulnerable to the illness and its complications, including pneumonia.

But health officials said they don't know why this year's vaccine did so poorly in that age group.

One theory, as yet unproven, is that older people's immune systems were accustomed to strains from the last two years and had more trouble switching gears to handle this year's different, harsh strain.

The preliminary data for senior citizens is less than definitive. It is based on fewer than 300 people scattered among five states.

But it will no doubt surprise many people that the effectiveness is that low, said Michael Osterholm, a University of Minnesota infectious-disease expert who has tried to draw attention to the need for a more effective flu vaccine.

Among infectious diseases, flu is considered one of the nation's leading killers. On average, about 24,000 Americans die each flu season, according to the CDC.

This flu season started in early December, a month earlier than usual, and peaked by the end of year. Hospitalization rates for people 65 and older have been some of the highest in a decade, at 146 per 100,000 people.

Flu viruses tend to mutate more quickly than others, so a new vaccine is formulated each year to target the strains expected to be the major threats. CDC officials have said that in formulating this year's vaccine, scientists accurately anticipated the strains that are circulating this season.

Because of the guesswork involved, scientists tend to set a lower bar for flu vaccine. While childhood vaccines against diseases like measles are expected to be 90 or 95 percent effective, a flu vaccine that's 60 to 70 percent effective in the U.S. is considered pretty good. By that standard, this year's vaccine is OK.

For senior citizens, a flu vaccine is considered pretty good if it's in the 30 to 40 percent range, said Dr. Arnold Monto, a University of Michigan flu expert.

A high-dose version of the flu shot was recently made available for those 65 and older, but the new study was too small to show whether that has made a difference.

The CDC estimates are based on about 2,700 people who got sick in December and January. The researchers traced back to see who had gotten shots and who hadn't. An earlier, smaller study put the vaccine's overall effectiveness at 62 percent, but other factors that might have influenced that figure weren't taken into account.

The CDC's Bresee said there is a danger in providing preliminary results because it may result in people doubting — or skipping — flu shots. But the figures were released to warn older people who got shots that they may still get sick and shouldn't ignore any serious flu-like symptoms, he said.

Las Vegas Shooting Launches Multi-State Manhunt

An argument in the valet area of a Las Vegas hotel led to a deadly drive-by shooting on the occupants of a Maserati on Vegas' glitzy strip, initiating a multi-state manhunt for the black Range Rover from which the shots were fired.

Three people were left dead in the attack, including two who died when their taxi was struck by the careening sports car and exploded into flames.

"What happened is not just tragic, but underscores the level of violence we see sometimes here in Las Vegas as well as across America," Las Vegas Metropolitan Sheriff Doug Gillespie said at a news conference today. "Clearly, the suspects in this shooting have no regard for the lives and safety of others."

The altercation took place in the valet area of the Aria resort and casino. Gillespie said there is currently "no indication" what the squabble was about.

Gillespie said that authorities do not know how many people are in the SUV, but that they are considered armed and dangerous. He warned members of the public to stay away from it.

"You should not take action," he said. "Instead, call your local police department and alert them to the whereabouts of the suspect vehicle."

Authorities in Nevada, Utah, Arizona and California are all on alert for the car.

"These individuals will be found," Gillespie said. "They will be prosecuted to the full extent of the law."

The Range Rover SUV shot at two people in the Maserati, which caused a multi-car crash. Police have not released the model of the Maserati, but the price of a new Maserati ranges from $123,000 to $142,000.

Police said that they believe a group of men riding in a black Range Rover Sport SUV pulled up alongside the Maserati around 4:20 a.m. today and fired shots into the car, striking the driver and passenger, according to Officer Jose Hernandez of the Las Vegas Metropolitan police department.

The Maserati then swerved through an intersection, hitting at least four other cars. One car that was struck, a taxi with a driver and passenger in it, caught on fire and burst into flames, trapping both occupants, Hernandez said.

The SUV then fled the scene, according to cops.

Gillespie said investigators are in the process of gathering video footage from hotels, casinos and the taxi cabs that were at the intersection.

The driver of the Maserati died from his gunshot wounds at University Medical Center shortly after the shooting, according to Sgt. John Sheahan.

The driver and passenger of the taxi both died in the car fire.

At least three individuals, including the passenger of the Maserati, were injured during the shooting and car crashes and taken to UMC hospital for treatment.

Authorities said the Maserati passenger, identified only as a man, sustained only a minor injury to his arm. He is speaking to and cooperating with police.

They do not yet know whether the cars had local plates or were from out of state.

No bystanders were hit by gunfire, Hernandez said.

"We're currently looking for a black Range Rover Sport, with large black rims and some sort of dealership advertising or advertisement plates," Hernandez said. "This is an armed and dangerous vehicle."

The Las Vegas Convention and Visitors Authority had no immediate comment about the safety of tourists in the wake of the shooting today.

French general urges EU to equip "impoverished" Mali army

BAMAKO, Mali (Reuters) - The European Union should complement a mission to train Mali's army, routed by rebels last year, by providing equipment from uniforms to vehicles and communications technology, a French general said on Wednesday.

General Francois Lecointre, appointed to head the EU training mission to Mali (EUTM) that was formally launched this week, said in Bamako equipping the "very impoverished" and disorganized Malian army was as important as training it.

Europe, along with the United States, has backed the French-led military intervention in Mali which since January 11 has driven al Qaeda-allied Islamist insurgents out of the main northern towns into remote mountains near Algeria's border.

European governments have ruled out sending combat troops to join French and African soldiers pursuing the Islamist rebels.

But the EU is providing a 500-strong multinational training force that will give military instruction to Malian soldiers for an initial period of 15 months at an estimated cost of 12.3 million euros ($16.45 million).

While hailing what he called the EU's "courageous, novel, historic" decision to support Mali, Lecointre told a news conference the Malian army's lack of equipment was a problem.

"I know the Malian state is poor, but the Malian army is more than poor," the French general told a news conference, adding that it urgently needed everything from uniforms and weapons to vehicles and communications equipment.

Last year, when Tuareg separatist forces swelled by weapons and fighters from the Libyan conflict swept out of the northern deserts, a demoralized and poorly-led Malian army collapsed and fled before them, abandoning arms and vehicles.

Mali's military was further shaken by a March 22 coup by junior officers who toppled President Amadou Toumani Toure, sowing division among rival army factions. Islamist radicals allied to al Qaeda later hijacked the victorious Tuareg rebellion to occupy the northern half of the country.

In a fast-charging military campaign led by Paris, French and African troops have driven the jihadists out of principal northern towns like Gao and Timbuktu, and are fighting the rebels in the Adrar des Ifoghas mountains.

HUMAN RIGHTS INSTRUCTION

Flanked by Mali's armed forces chief, General Ibrahima Dembele, Lecointre said he was disappointed that a meeting of international donors last month pledged funds for an African military force, known as AFISMA, being deployed in Mali, but included "very few" contributions for the Malian army itself.

"The European Union needs to invest today in the equipping of the Malian army and not just in its training," the general said, adding he would make this point strongly in a report to EU member state representatives early next month.

Asked how much re-equipping the army would cost, he said it would be "much more" than the 12 million euros of EU financing for the training mission, but could not give a precise estimate.

Starting early in April, the EU mission will start instructing Malian soldiers with a plan to train four new battalions of 600-700 members each, formed from existing enlisted men and new recruits.

Lecointre said the EU training would include instruction in human rights. Demands for this increased after allegations by Malian civilians and international human rights groups that Malian soldiers were executing Tuaregs and Arabs accused of collaborating with Islamist rebels.

The European training contingent is drawn from a range of European countries, but the main contributors would be France, Germany, Italy, Spain and Britain, EUTM officers said.

Mali's army has received foreign training before - several battalions that fled before the rebels last year were trained by the U.S. military and the leader of the March 22 coup, Captain Amadou Sanogo, attended training courses in the United States.

Dembele said U.S. training failed to forge cohesion among Malian units and he hoped the EU training would achieve this.

The United States, which halted direct support for the Malian military after last year's coup, could eventually resume aid if planned national elections in July fully restore democracy to the West African country.

Washington is providing airlift, refuelling and intelligence support to the French-led military intervention in Mali. ($1 = 0.7479 euros)

Qantas reports sharp rise in first-half profits

SYDNEY: Australian flag carrier Qantas on Thursday reported that first-half net profit more than doubled to A$111 million (US$114 million), also announcing an upgrade to its fleet.

The result in the six months to December 31 was up 164 percent on the same period in the previous year and in line with guidance, "despite challenging conditions in international and domestic air travel markets."

Underlying profit before tax -- the airline's preferred measure of financial performance -- was A$223 million, up 10 percent.

Qantas also announced an order for five new Boeing 737-800s and the upgrade of 20 Airbus A330-200s and 10 A330-300s.

The additional Boeing 737-800 aircraft are for the flag carrier's domestic service and for delivery during 2014, the company said in a statement, adding that leases on two existing B737-800s would be extended this year.

"The refurbished aircraft will give Qantas International a truly world-class product in global aviation's most dynamic and competitive market," chief executive Alan Joyce told a press conference.

"Growing with Asia is a major priority for the Qantas Group and this investment underpins our commitment to the region."

Joyce said: "Older narrow body Boeing 737-400s will be phased out by the end of 2013 and Boeing 767s by mid-2015.

"We are simplifying our fleet and making better use of the greater flexibility and higher frequencies that the B737-800s provide, while investing in what will be the best domestic onboard product anywhere in the world with the A330s."

The A330 reconfigurations and new orders will not affect planned capital expenditure of A$1.6 billion in 2012/13 and A$1.5 billion in 2013/14.

However, Qantas International reported an underlying before-tax loss of A$91 million in the six-month period, an improvement of A$171 million.

"Qantas International is well advanced in its turnaround plan," Joyce said.

"The 65 per cent improvement in Qantas International's underlying EBIT is testament to the steps taken to remove cost from the businesses, from closing down loss-making routes to retiring aircraft and consolidating operations."

Qantas is planning to broaden its reach in Asia as part of a strategy to turn around its struggling international arm.

The move is a consequence of its global alliance with Dubai-based Emirates, which means services to Asia will no longer be tied to onward links to Europe.

New direct destinations from Australia being considered include Beijing, Seoul, Mumbai, Delhi and Tokyo-Haneda at the same time as increasing capacity and frequency of flights to Hong Kong and Singapore.

Australia's competition watchdog last month gave Qantas and Emirates permission to launch their alliance in which the airlines will coordinate ticket prices and flight schedules.

Qantas will shift its hub for European flights to Dubai from Singapore and end a partnership with British Airways. The tie-up is seen as vital to the sustainability of Qantas, which last year posted its first annual deficit since privatisation in 1995 due to tough regional competition and high fuel costs.

West Bengal govt plans to depoliticize students' union polls

KOLKATA: Increasing incidence of violence on campuses in West Bengal has forced the Mamata Banerjee government to explore ways to depoliticise students' union elections. The state education department has drawn up a draft guideline that proposes to delink student bodies from political parties and make college union polls a 'once-in-two-years' event.

Education minister Bratya Basu is expected to submit the draft to chief minister Mamata Banerjee early next week. "Only after the chief minister's go-ahead, a final draft will be prepared and placed before the cabinet for approval," Basu told TOI on Wednesday.

The proposal comes barely a week after a policeman was shot dead during clashes between students' groups in a city college.

Calcutta University vice-chancellor Suranjan Das, higher education council chairman Sugata Marjit and the education minister have put their heads together to draw up the draft which will be put on the higher education department website on Thursday for stakeholders to give their suggestions.

The guidelines loosely follow the model of Bengal Engineering and Science University (Besu) where the student union has been replaced by a senate with several associate societies or clubs. The move has gone a long way in calming the restive Besu campus.

The latest move has been welcomed by academics. "This is an excellent attempt by the education minister. All my life, I have tried to propagate the idea to delink college politics from party politics. This is a move in the right direction. Now, the question is to implement the draft proposals," said former principal of Presidency College Amal Mukhopadhyay.

According to the draft, college elections will not be fought on political symbols. The student union will be renamed student council and its president will be nominated by the senior most teacher of the college. The vice-president will be nominated by the teachers' council. In case of universities, the vice-chancellor will select the president. The two vice-presidents will be nominated by the executive council and the court - the two top bodies in university administration.

The draft provides for election to the post of general secretary, assistant general secretary and five other secretaries who would look after student activities such as culture, drama, sports, etc. All students would either vote to elect these representatives as in the case of Jawaharlal Nehru University or Jadavpur University or the general secretary would be elected from among class representatives as is done in Calcutta University.

In keeping with the recommendations of the Lyngdoh Commission, an election observer will oversee the process and complete it within a month. The observer may wind up the entire process within 15 days, if he deems it fit.

Primacy has been given to the elected representatives. The elected general secretary will represent students in the college governing body while the general secretary of the students' council will make way to the university's highest body - the executive council.

The purpose is to integrate the students' bodies in the overall academic system rather than turning them into power centres of political parties.

Trinamool Congress Chhatra Parishad leader Shanku Deb Panda, however, reacted cautiously to the move. "We will have to see how far the guidelines can be implemented," he said.

"I have already sent the draft of the students' senate in Besu to the committee formed by the state government and our ideas have been appreciated. We will now wait to read the draft as prepared by the higher education department," said Ajay Ray, vice-chancellor of Besu.

Scientists use 3-D printing to help grow an ear

WASHINGTON (AP) — Printing out body parts? Cornell University researchers showed it's possible by creating a replacement ear using a 3-D printer and injections of living cells.

The work reported Wednesday is a first step toward one day growing customized new ears for children born with malformed ones, or people who lose one to accident or disease.

It's part of the hot field of tissue regeneration, trying to regrow all kinds of body parts. Scientists hope using 3-D printing technology might offer a speedier method with more lifelike results.

If it pans out, "this enables us to rapidly customize implants for whoever needs them," said Cornell biomedical engineer Lawrence Bonassar, who co-authored the research published online in the journal PLoS One.

This first-step work crafted a human-shaped ear that grew with cartilage from a cow, easier to obtain than human cartilage, especially the uniquely flexible kind that makes up ears. Study co-author Dr. Jason Spector of Weill Cornell Medical Center is working on the next step — how to cultivate enough of a child's remaining ear cartilage in the lab to grow an entirely new ear that could be implanted in the right spot.

Wednesday's report is "a nice advancement," said Dr. Anthony Atala, director of the Institute for Regenerative Medicine at Wake Forest Baptist Medical Center, who wasn't involved in the new research.

Three-dimensional printers, which gradually layer materials to form shapes, are widely used in manufacturing. For medicine, Atala said the ear work is part of broader research that shows "the technology now is at the point where we can in fact print these 3-dimensional structures and they do become functional over time."

Today, people who need a new ear often turn to prosthetics that require a rod to fasten to the head. For children, doctors sometimes fashion a new ear from the stiffer cartilage surrounding ribs, but it's a big operation. Spector said the end result seldom looks completely natural. Hence the quest to use a patient's own cells to grow a replacement ear.

The Cornell team started with a 3-D camera that rapidly rotates around a child's head for a picture of the existing ear to match. It beams the ear's geometry into a computer, without the mess of a traditional mold or the radiation if CT scans were used to measure ear anatomy.

"Kids aren't afraid of it," said Bonassar, who used his then-5-year-old twin daughters' healthy ears as models.

From that image, the 3-D printer produced a soft mold of the ear. Bonassar injected it with a special collagen gel that's full of cow cells that produce cartilage — forming a scaffolding. Over the next few weeks, cartilage grew to replace the collagen. At three months, it appeared to be a flexible and workable outer ear, the study concluded.

Now Bonassar's team can do the process even faster by using the living cells in that collagen gel as the printer's "ink." The 3-D technology directly layers the gel into just the right ear shape for cartilage to cover, without having to make a mold first.

The next step is to use a patient's own cells in the 3-D printing process. Spector, a reconstructive surgeon, is focusing on children born without a fully developed external ear, a condition called microtia. They have some ear cartilage-producing cells in that tissue, just not enough. So he's experimenting with ways to boost those cells in the lab, "so we can grow enough of them from that patient to make an ear," he explained.

That hurdle aside, cartilage may be the tissue most amenable to growing with the help of 3-D printing technology, he said. That's because cartilage doesn't need blood vessels growing inside it to survive.
