First cracks in the official London bombing story?

From MSNBC:

“Rejoice, Islamic nation. Rejoice, Arab world. The time has come for vengeance against the Zionist crusader government of Britain in response to the massacres Britain committed in Iraq and Afghanistan,” said the statement, translated by The Associated Press in Cairo. The AP was unable to access the Web site where it was posted, which was closed quickly after the reports.

But MSNBC TV translator Jacob Keryakes, who said that a copy of the message was later posted on a secular Web site, noted that the claim of responsibility contained an error in one of the Quranic verses it cited. That suggests that the claim may be phony, he said.

"This is not something al-Qaida would do," he said.
