A mob of Egyptian Salafists stormed a home full of Shia Muslim worshippers in Abu Mussalam, Egypt (near Cairo) brutally killing four of them. According to citizen journalist Hazem Barakat, women were inciting the violence, and no-one including police did anything about it. Barakat tried to get the Central Security Forces to intervene, to no avail. He has it all on tape.
They just can't get along.
