An al Qaeda “assassin” accused of bombing Christian churches and a luxury hotel in Pakistan 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 obtained by the whistleblowing website WikiLeaks.
The Algerian, who was captured in Pakistan in 2003, was described by interrogators as a “facilitator, courier, kidnapper, and assassin for al Qaeda”.
They also believed he had withheld important information from Canadian and British intelligence and (was) a “threat to US and allied personnel in Afghanistan  and Pakistan”.
