Terror suspect 'was British agent'
An al Qaida operative accused of bombing Christian churches and a luxury hotel in Pakistan in 2002 was working for British intelligence at the same time, according to leaked files.
The claim about Adil Hadi al Jazairi Bin Hamlili is made in secret reports on detainees at the US military's Guantanamo Bay prison camp.
The Algerian citizen, captured in Pakistan in 2003, was described by interrogators as a "facilitator, courier, kidnapper, and assassin for al Qaida".
But the Americans also believed he had "withheld important information from the Canadian Secret Intelligence Service and British Secret Intelligence Service ... and (was) a threat to US and allied personnel in Afghanistan and Pakistan".
The files, handed to the Guardian and Daily Telegraph by whistleblowing website WikiLeaks, also indicate that at least 35 terrorists incarcerated at Guantanamo Bay went to fight against the West after being radicalised by extremist preachers in the UK.
Abu Qatada and Abu Hamza are identified in the documents as key recruiters responsible for sending dozens of extremists from throughout the world to Pakistan and Afghanistan via London mosques.
Meanwhile, The Guardian claims the leaked documents also reveal that a Guantanamo Bay detainee was freed after informing on 123 other prisoners.
The report said that the Yemeni man captured in Pakistan in December 2001 gave detailed information about al-Qaida activity and identified other detainees as militants.
However, the documents say some of his claims could not be verified.
The Pentagon has condemned the publication of the documents.
