Ansar Al-Sunna has posted a video of the attack on the US base FOB Marez in Mosul. Astonishingly, they filmed the actual explosion, then drove around the base in order to get a good shot of the gaping hole in the tent. They introduce the tape with a segment in which an Ansar al-Sunna fighter uses a map of the base to show how the attack was accomplished. The bomber is shown receiving farewell hugs before departing on his mission.
For the atttackers to be so brazen shows how unprepared the US forces are.
