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.

Furthermore, the website posting doesn't even claim personal responsibility, it simply references "the heroic mujahedeen" in the third person. The posting praises the attack, it doesn't even take responsibility for it.

These facts didn't stop countless newspapers and Neo-Con websites automatically assuming Al-Qaeda (or Al-CIAda) was behind the attack.
