An al-Qaida 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 military's Guantánamo Bay prison camp.
Adil Hadi al Jazairi Bin Hamlili, an Algerian citizen described as a "facilitator, courier, kidnapper, and assassin for al-Qaida", was detained in Pakistan in 2003 and later sent to Guantánamo Bay.
But according to Hamlili's Guantánamo "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".
