Obama watched Bin Laden die on live video as shoot-out beamed to White House !!!!!

· Obama watched assault on compound housing Bin Laden in real time

· Compound was yards from Pakistan's 'Sandhurst' military academy

· DNA tests 99.9 per cent certain man killed WAS Bin Laden

· U.S. embassies on alert over Al Qaeda reprisal attacks

· Obama and George W. Bush both declare: 'Justice has been done'

President Obama was watching on a TV screen as a commando gunned down Osama bin Laden. Via a video camera fixed to the helmet of a U.S. Navy Seal, the leader of the free world saw the terror chief shot in the left eye.

The Seal then carried out what is known in the military as a ‘double tap’ – shooting him again, probably in the chest, to make certain he was dead.

The footage of the battle in Bin Laden’s Pakistani hideout – which played out like an episode of 24 – is said to show one of his wives acting as a human shield to protect him as he blasted away with an AK47 assault rifle.

She died, along with three other men, including one of Bin Laden’s sons. Within hours, the Al Qaeda leader’s body was buried at sea.

Despite President Obama claiming the master terrorist’s death made the world a ‘safer, better place’, the head of the Central Intelligence Agency declared that terrorists would ‘almost certainly’ respond.

The warning came on a day when:

■ Relations between Pakistan and the West were under intense strain amid disbelief that intelligence chiefs in Islamabad had no idea Bin Laden was living in a compound only 800 yards from the country’s leading military academy.

■ U.S. officials sought to justify the torture of detainees at Guantanamo Bay by claiming it provided the crucial breakthrough in hunting down Bin Laden.

■ It emerged that a terror operative captured in Pakistan in 2004 said Al Qaeda would detonate a nuclear bomb in the U.S. if Bin Laden were killed or captured.

David Cameron said Bin Laden’s death would be ‘welcomed right across our country’.

But security was stepped up as he warned: ‘It does not mark the end of the threat we face from extremist terrorism. Indeed, we will have to be particularly vigilant in the weeks ahead.’

Last night the Prime Minister chaired a meeting of the Government’s emergency planning committee Cobra to assess the implications for the UK. Security sources have been told of specific threats against targets in North Africa and Europe.

Officials in Britain fear a ‘lone wolf’ – currently off the security services’ radar – could be inspired to take revenge.

There is no specific intelligence pointing to any attack in response to Bin Laden’s death, but it is ‘common sense’ to be on guard, Whitehall officials say.

Possible targets include popular tourist and business locations including the Houses of Parliament, Canary Wharf and the London Eye, say security experts.

President Obama announced Bin Laden’s death in a televised statement shortly after 4am British time yesterday

He recalled the images from the terror attacks of September 11, 2001 which were ‘seared into our national memory’.

Nearly 3,000 people were killed – including 67 Britons – when four jets hijacked by Al Qaeda extremists crashed in New York, Washington and Pennsylvania. The attack left ‘a gaping hole in our hearts’, said the President.

Last night pictures were released of Mr Obama and his security team – including Hillary Clinton – watching the mission to kill Bin Laden in the White House’s Situation Room – relayed to the White House by satellite – which played out like an episode of TV show 24 featuring fictional counter-terrorism agent Jack Bauer.
