Video purported to show the Iranian gunman who shot 7 students to death.
In grainy cellphone video, the gunman in a blue shirt is seen leaning out of a window with an AK-47, apparently firing rounds into people down below who were reportedly trying to break into the building. A few seconds after the shooting stops, a Molotov cocktail hits somewhere near the window and fire erupts, followed a few seconds later by cheers.
