British authorities learn of the arrest of top Islamist militant Djamel Beghal in Dubai (see July 24 or 28, 2001), and the CIA tells them that an operative behind a plot Beghal is helping organize, a bombing of the US embassy in Paris, has arrived in Britain. [Tenet, 2007, pp. 157] It is unknown who the operative behind the plot is and what action British authorities take on the matter, but arrests of people linked to Beghal and his associates are made around Europe in the next few months (see September 13, 2001, September 26, 2001 and March 2000-September 22, 2001). Beghal has been active in Britain for some time, in particular at London’s radical Finsbury Park mosque, which is under surveillance by the British (see 1997), and a group of his associates are arrested in Britain one day after his capture is made public (see March 2000-September 22, 2001). However, no action is taken against one of his key associates, Abu Hamza al-Masri, who is an informer for the British (see Early 1997). Authors Sean O’Niell and Daniel McGrory will comment: “Despite Beghal’s clear links to operations in London and Leicester, however, there was no search of the [mosque] building and no attempt to arrest the chief recruiter [Abu Hamza] who had led the prayers there. The mosque continued to be at the centre of jihad recruitment.” [O’Neill and McGrory, 2006, pp. 94]
