Egyptian protesters on Monday stormed the headquarters of the powerful Muslim Brotherhood after deadly clashes there between supporters and opponents of President Mohamed Morsi who hails from the group, an AFP correspondent said. The building in Cairo\'s Moqattam district was set ablaze before people stormed inside and began throwing things out of the windows, as others were seen leaving with items including furniture. Witnesses told AFP there were no Brotherhood members still inside the building, after they were escorted out by a group of people early on Monday.
