Egypt security forces have "cleared" a Cairo mosque after a two-day standoff with protestors, arresting many of the demonstrators inside. Earlier, troops stormed the al-Fath mosque where over 700 Morsi supporters had barricaded themselves on Saturday, one day after 173 people died nationwide in clashes between protestors and government forces. Witnesses describe troops firing tear gas into the building. Those inside were being offered safe passage if they submitted to investigation in an army camp—however, those inside insisted on such investigations being conducted inside the building, prior to leaving. Meanwhile, the military-backed interim government has proposed a plan outlawing the Muslim Brotherhood's political party.
