• Intelligence experts are now examining Al Qaeda leader's computer hard drive

The astonishing story of how the U.S. finally tracked down Osama Bin Laden was revealed today after U.S. forces were led to him by his most trusted courier - a Kuwaiti-born man named Sheikh Abu Ahmed.
The shadowy figure was identified after Al Qaeda commanders held at Guantanamo Bay admitted they knew him - and that he had connections to the Saudi Arabian-born leader.
Once U.S. security forces had that information, they flooded Pakistan with agents desperate to pick up a trace of him, he would lead them to the lair of the world's most wanted man.
But the confessions were only the start of an extraordinary manhunt which stretched from the prison camp in Cuba to Peshawar in Pakistan and finally ended in a deadly shootout at the Al Qaeda commander's luxury compound. 
For many years, Ahmed was only known by his 'nom de guerre', Abu Ahmed al-Kuwaiti.

The first indications about his significance came from CIA detainees shortly after the 9/11 terror attacks.

Scene of the assassination: Journalists and camera crews outside the compound in the town of Abbottabad, Pakistan, where Osama bin Laden was killed by U.S. special forces after President Obama gave the order to take out the terrorist mastermind

Seen better days: Pakistani soldiers in a jeep pass by the compound, close to a military academy and less than 70 miles from capital Islamabad, is said to be worth $1m although it appears in a state of some disrepair

Surrounded: The three-storey lair, guarded left by security officials, is encircled by walls 12ft high topped with three lines of barbed wire. Local workers were seen carrying out running repairs after the raid which ended with four people - including Bin Laden - dead

Unnoticed: The compound was home to Bin Laden and up to 17 members of his extended family

They identified him as one of Bin Laden's couriers, an aide the terror chief trusted with his life. But details were scant and agents quickly found the trail went cold. 
It was not until 2004, when Al Qaeda operative Hassan Ghul was captured in Iraq, that the CIA began to make progress.
Ghul told the intelligence service that al-Kuwaiti was a courier and that he was close to Faraj al-Libi, Al Qaeda's operational commander, who replaced Khalid Sheikh Mohammed.The pace of the pursuit then picked when U.S. soldiers captured al-Libi.
Under CIA interrogation, al-Libi admitted that when he was promoted to succeed Mohammed, he received the word through a courier.

In 2004, a captured Al Qaeda operative told U.S. intelligence that the courier Sheikh Abu Ahmed was close to operational commander Faraj Al-Libi, who had replaced Khalid Sheikh Mohammed. He admitted his existence in Guantanamo Bay - convincing Washington they were finally on to Bin Laden's tail

But he made up a name for the courier and denied knowing al-Kuwaiti, a denial that was so adamant and unbelievable that the CIA took it as a lie.
Finally, Khalid Sheikh Mohammed himself admitted that he knew the courier. Held at Guantanamo Bay, he had been waterboarded 183 times without identifiying Ahmed.
It was only later under conventional interrogation techniques that he admitted he knew him - though he still did not surrender a full name or where the courier could be found.
The CIA were now convinced that if they found Abu Ahmed they would find Bin Laden.
Scores of agents scoured Pakistan and Afghanistan for the merest whisper of Ahmed's whereabouts.

Blackened: A shelter in the compound appears to have take some of the fire as U.S. forces went into to grab Bin Laden

Sightseeing: Local residents gather outside and atop the walls Bin Laden's home while the security services turn a blind eye

Protest: Hundreds of people gathered in Karachi in Pakistan to chant slogans condemning the killing of Osama Bin Laden and offer funeral prayers

His family, still in the Arabian Gulf, were traced, their communications monitored and it was from this surveillance that the CIA finally got his full name and an idea of his location.
When Ahmed was finally tracked down, he was driving a white Suzuki in Peshawar, a frontier town with a high population of Al Qaeda sympathisers.
CIA agents followed him to a compound in the northeast Pakistani town of Abbottabad, where al-Libi had once lived. It had 18ft high walls, barbed wire, and no telephone or internet connections.
Without confirmation and with little to go on, the CIA became convinced they had finally found the world's most wanted man.

Crash site: The remains of the U.S. military chopper which special forces were unable to start after carrying out the hit can be seen clearly lying in the compound

THE 'SECRET' SECRET AGENCY

The operation that led to the death of Osama Bin Laden has thrown the spotlight on a lesser known U.S. spy agency.

For eight months the National Counterterrorism Center (NCTC) used satellites and unmanned drones to continuously track the courier who led the U.S. to Bin Laden.

The NCTC, based in a normal-looking office building in Rosslyn, Virginia, doesn't have the high-profile of CIA but proved ruthlessly effective when it mattered.

It was the NCTC that produced a 'map' of Bin Laden's bunker, enabling the Joint Special Operations Command Targeting and Analysis Center build a complete replica of the compound at Bagram airbase in order to rehearse the operation to perfection. 

Details of the NCTC's operation are classified but a senior intelligence official, who paid tribute to its work on condition of anonymity, said the depth of the information supplied was vital to the operation's success.

'The operators who assaulted the compound felt they had all the intelligence they needed,’ the source told the Huffington Post, adding that in similar operations the elite teams rarely ever believe they have 'enough' intelligence.

The reaction to this operation is a far cry from the one that greeted the U.S. intelligence services in 2001 for their failure to prevent the September 11 atrocity, with a lack of inter-departmental communication particularly noted.

But James R. Clapper, the director or national intelligence who oversees all 16 of the country's agencies, released a statement which pointed out 'Never have I seen a more remarkable example of focused integration, seamless collaboration and sheer professional magnificence, than was the case in the killing of Bin Laden.

By February this year they were ready to act. They initially considered bombing the site to smithereens - but Barack Obama rejected the plan as there would be no proof Bin Laden was dead.
And then there were additional complications.
America's strained relationship with Pakistan was plunged into fresh turmoil by the arrest of Raymond Davis, a CIA contractor who had shot dead two Pakistanis in January.
U.S. officials feared that he would be killed if Bin Laden was executed. A tense few weeks ensued until Davis's release on March 16.
Then there was the matter of WikiLeaks. Just weeks before Sunday night's raid, the whistleblower website had published a tranche of new secret documents.
These made reference to named ‘couriers’ carrying Bin Laden’s message to his followers, and also to Abbottabad as a possible Al Qaeda bolthole.
There was a real risk that Bin Laden would flee once again, thwarting U.S. attempts to capture or kill him
In the early hours of May 1,  two dozen members of the Navy's elite SEAL Team Six went in.
Bin Laden was shot twice, once through the head. His daughter, 12, watched him die.
Three others also died - a woman who is said to have been used as a human shield and Ahmed's brother among them.
The squad left the compound with a trove of computers and files. CIA chief Leon Panetta has set up a task force to act on fresh intelligence gleaned.
He said the U.S. had collected an “impressive amount” of material from bin Laden’s compound, mostly electronics.

Ahmed himself, Bin Laden's closest lieutenant, who had finally given him away, was also killed.
Today, it emerged that there were 17-18 people in the compound at the time of the attack and the Navy Seals cans took away one person still alive who could be a Bin Laden son
Those who survived the attack included a wife, a daughter and eight to nine other children who did not belong to Bin Laden. They were tied up taken away by the troops.
U.S. officials believe that Bin Laden had lived within the blacked-out for up to six years. He had been living in Afghanistan before a 2001 U.S. invasion helped topple its Taliban regime.
'Well I think the latest information is that he was in this compound for the past five or six years and he had virtually no interaction with others outside that compound. But yet he seemed to be very active inside the compound,' White House counterterrorism chief John Brennan said.
'And we know that he had released videos and audios. We know that he was in contact with some senior al Qaeda officials,' Brennan added.
'So what we're trying to do now is to understand what he has been involved in over the past several years, exploit whatever information we were able to get at the compound and take that information and continue our efforts to destroy al Qaeda.'
