The Associated Press (AP) reports that an unmanned spy plane and three helicopters were overhead during the raid. In recent months, the US has stepped up its use of drones to fire missiles at Al Qaeda leaders and other targets along the Afghan-Pakistani border. Pakistan has objected to the violation of its airspace. Wednesday's raid involved close cooperation with US officials, though none have commented publicly. Pakistan's Army has so far declined to comment.
Pakistani intelligence officials told AP and Reuters that Taifi, the detained Saudi, played a role in the 2005 attacks in London, when four British Islamists carried out suicide bombings that killed 52 people. Some of the bombers had visited Pakistan and trained with militants there.
