A second group has "taken credit" for the London bombings:
A group that claimed last year's Madrid train bombings in the name of al-Qaeda today said it was also behind blasts in London that killed at least 50 people and injured 700 two days ago, according to an Islamist Web site.
The statement attributed to the Abu Hafs al-Masri Brigades' Europe section is the second in which a group purporting to be part of al-Qaeda has said it carried out the bombings of three London Underground trains and a bus.
``A group of mujahedeen from a division of the Abu Hafs al- Masri Brigades piled blow after blow on the infidel capital, the British capital, leaving dead and injured,'' according to the latest statement. ``First there was Madrid, then Istanbul, and now London, and tomorrow the mujahedeen will have other words to say.'' The statement has not been verified by authorities.
The Saudis attribute the attack to an Al Qaeda sleeper cell.
