As noted earlier today, the Pentagon announced the capture of an important Al Qaeda leader, Abd al-Hadi al-Iraqi. Tonight the Times Online reports that al-Iraqi is believed to be the mastermind behind the 7/7 bombings in London.

The al-Qaeda leader who is thought to have devised the plan for the July 7 suicide bombings in London and an array of terrorist plots against Britain has been captured by the Americans.

Abd al-Hadi al-Iraqi, a former major in Saddam Hussein’s army, was apprehended as he tried to enter Iraq from Iran and was transferred this week to the “high-value detainee programme” at Guantanamo Bay.

Abd al-Hadi was taken into CIA custody last year, it emerged from US intelligence sources yesterday, in a move which suggests that he was interrogated for months in a “ghost prison” before being transferred to the internment camp in Cuba.

Abd al-Hadi, 45, was regarded as one of al-Qaeda’s most experienced, most intelligent and most ruthless commanders. Senior counter-terrorism sources told The Times that he was the man who, in 2003, identified Britain as the key battleground for exporting al-Qaeda’s holy war to Europe.

Abd al-Hadi recognised the potential for turning young Muslim radicals from Britain who wanted to become mujahidin in Afghanistan or Iraq into terrorists who could carry out attacks in their home country. He realised that their knowledge of Britain, possession of British passports and natural command of English made them ideal recruits. After al-Qaeda restructured its operations in Pakistan’s tribal areas he sought out young Britons for instruction at training camps. In late 2004 Abd al-Hadi met Mohammad Sidique Khan and Shehzad Tanweer, from Leeds, at a militant camp in Pakistan and, in the words of a senior investigator, “retasked them” to become suicide bombers.

They were sent back to Britain where they led the terrorist cell that carried out the 7/7 bombings, killing 52 Tube and bus passengers.
