An Islamist Web site posted a statement purporting to be from an al-Qaeda-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 Islamist Web site where similar claims for responsibility have appeared in the past.
"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 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."
