Zawahri video: London bombers trained by al-Qaida

Two of the four suicide bombers who attacked London a year ago had spent time at an al-Qaida camp to prepare themselves for a suicide attack, the deputy leader of al-Qaida said in an Internet video Friday. Ayman al-Zawahri said on the video that Shehzad Tanweer and Mohammad Sidique Khan had come to a base of al-Qaida. It was known that the two British Muslims from north England had visited Pakistan, but al-Zawahri's comment was the first confirmation that they had been to al-Qaida camps. "Both of them were seeking martyrdom and wished that they could carry out a martyrdom operation," al-Zawahri said, using the Islamic euphemism for a suicide attack.
