Al Qaeda carried out the July suicide bombings in London to strike at “British arrogance,” the group’s second-in-command Ayman al-Zawahri said in a video tape aired on Arab satellite channel Al Jazeera on Monday.

“The London attack is one of the attacks that al Qaeda ... had the honor of carrying out against ... British arrogance, the aggression of the crusader British against the Muslim nation for over a hundred years,” Zawahri said.
