Shared by Egyptocracy on Twitter, the video below was taken in Alexandria, showing local teenagers hiding on a roof as pro-Morsi supporters at least one carrying an al-Qaeda flag, throw rocks at them, then climb up, toss the kids off then beating their unmoving bodies with sticks.
Close up view of the pro-Morsi protester with the al-Qaeda flag caught from the video above as it was unfurled.
