US rushes troops to Haiti earthquake zone

The US is sending up to 3,500 soldiers and 2,200 marines to Haiti to help rescue efforts in the wake of the devastating earthquake.

President Barack Obama pledged one of the biggest relief efforts in recent US history and said Haiti would "not be forgotten" in its hour of need.

The search for survivors continues but rescuers lack heavy lifting equipment and many are using their bare hands.

The Red Cross estimates 45,000-50,000 people are dead and up to 3m affected.

BBC correspondents say the situation is increasingly desperate, with aid only trickling in.

Mr Obama confirmed that some US rescuers were already working on the ground in Haiti.

Speaking in Washington, he promised the country "every element of our national capacity, our diplomacy, and development assistance, the power of our military and most importantly, the compassion of our country" following the disaster.

"To the people of Haiti, we say clearly and with conviction, you will not be forsaken, you will not be forgotten," he said.

However he warned it would take time for much-needed help to reach people.

Mr Obama also promised an immediate $100m for Haiti's relief effort and said that investment would grow over the coming year to aid long-term recovery.

The first 100-strong contingent from the US Army's 82nd Airborne Division is expected to arrive in Haiti by the end of Thursday, with several hundred more due by Friday.

The USS Carl Vinson aircraft carrier will arrive on Thursday. The USS Bataan, carrying a marine expeditionary unit, is also on its way.

The US forces will join Haitians and international search and rescue teams already on the ground.

Aid groups say it is a race against time to find people trapped under the rubble of the collapsed buildings.

Elisabeth Byrs, of the UN's Office for the Coordination of Humanitarian Affairs, said: "The priority is to find survivors. We are working against the clock."

The head of Medecins du Monde, Olivier Bernard, told AFP news agency that aid had to arrive by Thursday evening.

"To save lives, surgery must be available ideally within the first 48 hours," he said.

Doctor's assistant Jimitre Coquillon told Associated Press: "This is much worse than a hurricane. There's no water. There's nothing. Thirsty people are going to die."

The BBC's Matthew Price in Port-au-Prince says Haiti is in massive need of food, water and medicine, as well as bulldozers and heavy lifting equipment.

But perhaps more than anything it needs someone to take charge here, our correspondent says. The government is fragile at the best of times and there is no sense it is able to do anything for now.

Meanwhile, the US Federal Aviation Authority said it had stopped civilian flights to Haiti for the moment at the Haitian government's request because there was not enough space on the ground for more planes and only limited fuel for them to leave.

The director of Port-au-Prince's general hospital said that by 1100 (1600 GMT) at least 1,500 bodies were already stacked inside and outside the morgue, with police continuing to bring more corpses on pick-up trucks, Reuters reports.

UN Secretary General Ban Ki-moon said it could be days before even an estimate of the death toll from the earthquake could be made, but said he feared it would be "very high".

Up to 150 UN staff remain unaccounted for following the collapse of the UN headquarters building in Port-au-Prince and 36 UN military and police personnel are now confirmed dead.

On a note of hope, he recounted the survival of an Estonian UN official who was detected under 4m (13ft) of rubble after scratching noises were heard. He was dug out and is now in hospital.

A few US aid planes and a 50-strong Chinese rescue team with sniffer dogs have landed at the airport serving the capital, Port-au-Prince.

Cuba already had more than 300 doctors in Haiti before the earthquake and they have been treating the injured in field hospitals.

Other plane-loads of rescuers and relief supplies are on the way from the EU, Canada, Russia and Latin American nations.

A British rescue team with heavy lifting gear and dogs has now arrived in Haiti.

UK Prime Minister Gordon Brown said: "The last 24 hours have been truly horrific for the people of Haiti. It's a catastrophe that's still unravelling, it's a tragedy beyond imagination."

US Secretary of State Hillary Clinton cancelled a trip to Asia to deal with the crisis. She said there were tens of thousands of casualties in Haiti and that tens of thousands of buildings had collapsed.

"This is going to be a long-term effort," she said.

Her husband, Bill Clinton, the UN special envoy for Haiti, told the Washington Post the quake was "one of the great humanitarian emergencies in the history of the Americas".

Meanwhile, French President Nicolas Sarkozy called for an international conference on rebuilding Haiti to be held with the help of nations including the US, Brazil and Canada.

"Haiti must not remain a battered country," he said.

The World Bank is funding $100m of emergency aid. The World Food Programme is working on supplying 15,000 tonnes of food and the Red Cross has begun a $10m appeal.

Nigeria sect violence victims 'mostly children'

The Red Cross in Nigeria says many of those who were killed in clashes on Monday between troops and members of an Islamist sect in Bauchi were children.

Adamu Abubakar, its representative in the northern state, told the BBC 39 people had died - some 60% of them students aged between nine and 15.

Local officials said if any children had died, it would have been because they were hit by vehicles or trampled.

Twenty members of the Kala Kato sect had been arrested, Mr Abubakar said.

The fighting started when locals called in the authorities after members of the sect broke a ban on open-air preaching, which was introduced after an uprising earlier this year by the Boko Haram sect.

Hundreds died in the subsequent fighting across northern Nigeria.

'Result of preaching'

Mr Abubakar told the BBC's Focus on Africa programme the death toll from Monday's violence was 39. Sixteen people were also admitted to hospital, among them a seven-year-old who died on Tuesday morning, he added.

He said some of the victims had been shot, but most had been attacked with machetes and knives.

The Red Cross representative said the crisis "was the result of preaching" at an open-air gathering, after which members of the Kala Kato sect threatened to kill locals who would not join them or leave the area.

An army officer who was sent from a nearby base to speak to the sect's leaders was killed with a machete, he added.

Mr Abubakar said most of the dead were children from outside Bauchi who had been sent to study Arabic and the Koran with local clerics.

But a spokesman for the government of Bauchi, Alhaji Sanusi Mohammed, told the BBC that 32 people had died in the violence, and that most of the people killed were adult members of the sect who had attacked the security forces.

"Most likely, those children that might have been killed were probably crushed when running away from the scene, or they were victims of head-on collisions with cars," he said.

"But I definitely don't think it was security officers that went to quell the rioting who shot them down."

It was impossible that the troops had used machetes, he added.

Mr Mohammed said the clashes had been a result of a "misunderstanding within the religious sect" about its leadership, and that it had quickly escalated.

Correspondents say Kala Kato is a non-conformist sect made up of poor tradesmen, labourers and other working people.

Iran troops 'seize Iraq oil well'

Iranian troops have entered southern Iraqi territory and taken control of an oil well, reports say.

An Iraqi official played down the incident, saying the area was abandoned and right on a disputed border section.

Iranian soldiers crossed the border and raised an Iranian flag over the Fakkah oil field, a US military spokesman told the AFP news agency.

But an Iranian oil company spokesman denied the accusation, saying no troops had taken control of any oil well.

"The company denies Iranian soldiers taking control of any oil well inside Iraqi territory," the National Iranian Oil Company spokesman was quoted as saying by Iranian media.

Confirmation

Iraq's Deputy Interior Minister confirmed the Iranians stayed in Iraq and were in control of the well.

Earlier it was reported that they had withdrawn back across the border.

Deputy Interior Minister Ahmed Ali al-Khafaji initially told the Reuters news agency the reports of the Iranian incursion were not true.

But Mr Khafaji later confirmed the incursion had taken place, and said 11 Iranians had dug-in at the oil well and had not left.

"At 3:30 this afternoon, 11 Iranian soldiers infiltrated the Iran-Iraq border and took control of the oil well. They raised the Iranian flag, and they are still there until this moment," he told the Reuters news agency.

He said there had been no military response from Iraqi forces..

"We are awaiting orders from our leader," he said.

The incursion is one of several that have occurred in the last few days, he said.

The well is about 500m from an Iranian border fort and about 1km from an Iraqi fort, US Colonel Peter Newell told AFP.
