Five people were killed in clashes on Friday as supporters of deposed President Mohamed Mursi took to the streets of Cairo and other cities to demand the end of army-backed rule. The marches were the most ambitious attempt by the Muslim Brotherhood to press its demands since August 14, when authorities smashed two pro-Mursi sit-ins in Cairo and then declared a state of emergency and imposed a curfew.
