On 1 September it was reported that al-Qaeda officially claimed responsibility for the attacks in a videotape broadcast by the Arab television network Al Jazeera. However, an official inquiry by the British government reported that the tape claiming responsibility had been edited after the attacks, and that the bombers did not have direct assistance from al-Qaeda. Zabi uk-Taifi, an al-Qaeda commander arrested in Pakistan in January 2009, may have had connections to the bombings, according to Pakistani intelligence sources. More recently, documents found by German authorities on a terrorist suspect arrested in Berlin in May 2011 have suggested that Rashid Rauf, a British al Qaeda operative, played a key role in planning the attacks.
