Oddly enough, however, neither this group nor the first one that claimed responsibility was made up of Christian fundamentalists. From AP, with thanks to Mackie:
CAIRO, Egypt (AP) – An Islamic Web site posted a statement purporting to be from an al-Qaida-linked group Saturday in which it claimed responsibility for the bombings that killed at least 49 people in London and promised more attacks in the city it described as the “capital of the infidels.”
The claim purportedly from the Abu Hafs al Masri Brigade was logged on an Islamic Web site where similar claims for responsibility have appeared in the past. The statement’s authenticity could not be verified.
Experts say the group has no proven history of attacks and said it had claimed responsibility for events in which it was unlikely to have played any role, such as the 2003 blackouts in the United States and London that resulted from technical problems. In recent months it has also made threats that its operatives would strike in Europe if countries there did not withdraw troops from Afghanistan and Iraq.
“Our words have not gone with the wind and our strikes have not stopped. Thanks to God, a group of Mujahedeen from the Abu Hafs al Masri Brigades launched strike after strike in the capital of the Kufr, the infidels,” the statement said.
“Blessed is this conquest. The coming days will show a greater expression of jihad (holy war) against those who declared war against Islam and Muslims,” it said. “We will not keep quiet or stay idle until Islam is safe in the lands of Iraq, Afghanistan and Palestine.”
The statement was posted on a Web site run by Mohammad al-Masaari, a well known Saudi Islamic activist living in exile in London.
