LONDON (INP) - An Al-Qaeda operative accused of bombing two Christian churches and a luxury hotel in Pakistan in 2002 was at the same time working for British intelligence, according to secret files on detainees who were shipped to the US militarys Guantnamo Bay prison camp. Adil Hadi al Jazairi Bin Hamlili, an Algerian citizen described as a facilitator, courier, kidnapper, and assassin for al-Qaeda, was detained in Pakistan in 2003 and later sent to Guantanamo Bay. But according to Hamlilis Guantanamo assessment file, one of 759 individual dossiers obtained by the Guardian, US interrogators were convinced that he was simultaneously acting as an informer for British and Canadian intelligence. After his capture in June 2003 Hamlili was transferred to Bagram detention centre, north of Kabul, where he underwent numerous custodial interviews with CIA personnel. They found him to have withheld important information from the Canadian Secret Intelligence Service and British Secret Intelligence Service and to be a threat to US and allied personnel in Afghanistan and Pakistan. According to the files, Hamlili told his American interrogators at Bagram that he had been running a carpet business from Peshawar, exporting as far afield as Dubai following the 9/11 attacks. But his CIA captors knew the Algerian had been an informant for MI6 and Canadas Secret Intelligence Service for over three years - and suspected he had been double-crossing handlers. According to US intelligence, the two spy agencies recruited Hamlili as a humint - human intelligence - source in December 2000 because of his connections to members of various al-Qaeda linked terrorist groups that operated in Afghanistan and Pakistan. The files do not specify what information Hamlili withheld. But they do contain intelligence reports, albeit flawed ones, that link the Algerian to three major terrorist attacks in Pakistan during this time.
