the Abu Hafs al-Masri Brigades I don't think these are the real guys. They put out the first letter that gained notoriety, but it might have been a hoax. They also claimed responsibility for the American blackout.
This group did not put out the videotape of the Moroccan claiming responsibility.
Let's see if the press examines it closely.
I think that the Abu Hafs al-Masri Brigades is the real deal and that the blackout was more indicative of the conspiracy-prone mentality of the Arab mindset than anything else.
My guess is that these communiques are being written up by one of the organization's front groups out in London. The attacks they took credit for Baghdad and Turkey WERE al-Qaeda strikes.
