(AP Photo) The CIA thinks the next attempt to launch a 9/11-level attack is likely to come out of Britain and has informed President Obama of a huge new spy operation within the UK, intelligence sources tell the Daily Telegraph. Agents say the most likely theoretical culprit is British-born Pakistani extremist entering the US through the visa waiver program. Four of every 10 CIA counterterrorism operations are now conducted against targets in Britain, says one source, a number that has grown in the wake of the Mumbai attacks. Lashkar-e-Taiba is now seen as a threat on par with al-Qaeda, and it has a major penetration in the UK’s Pakistani Diaspora communities. As a result, the CIA now has a record number of informants in those communities. Read These Next One critical island in Iran has remained unscathed in airstrikes.
