A string of bombings hit police around Cairo on Friday, including a suicide car blast that ripped through the city's main police headquarters and wrecked a nearby museum of Islamic artifacts. Five people were killed in the most significant attack yet in the Egyptian capital at a time of mounting confrontation between Islamists and the military-backed government.
The blasts further hike tensions a day before the third anniversary of Egypt's 2011 uprising that toppled autocrat Hosni Mubarak — when supporters of the military and their Islamist opponents have each vowed rival rallies in the streets to press their cause. (AP)
