Passage: Upon his release from prison in 1995, he joined the Brixton Mosque. He later began attending the Finsbury Park Mosque in North London, headed at that time by the anti-American cleric Abu Hamza al-Masri and described as "the heart of the extremist Islamic culture" in Britain. By 1998 Reid was voicing extremist views. At the Finsbury Park Mosque he fell under the sway of "terrorist talent spotters and handlers" allied with al-Qaeda, including Djamal Beghal, one of the leaders of the foiled plan for a 2001 suicide bombing of the American Embassy in Paris. He spent 1999 and 2000 in Pakistan and trained at a terrorist camp in Afghanistan, according to several informants. He may also have attended an anti-American religious training centre in Lahore as a follower of Mubarak Ali Gilani. After his return to Britain, Reid worked to obtain duplicate passports from British government consulates abroad. He lived and travelled in several places in Europe, communicating via an address in Peshawar, Pakistan, in July 2001, Reid flew to Israel.
