Muslim Brotherhood Storm Cairo Government Building

CAIRO, Aug 15 (Reuters) - Hundreds of supporters of Egypt's Muslim Brotherhood stormed a government building in Cairo and set a fire at its entrance despite a crackdown on the movement by security forces, state TV and witnesses said.

More than 500 people were killed in violence on Wednesday which began when security forces broke up the Muslim Brotherhood's protest sit-ins in Cairo. (Reporting by Yasmine Saleh; Editing by Janet Lawrence)
