At Least Six Killed in Bombings Across Cairo

Government blames Muslim Brotherhood

A string of four bombings hit around Cairo on Friday, including a car blast that ripped through the Egyptian capital's main security headquarters and wrecked a nearby museum of Islamic artifacts. Six people were killed in the most significant attack yet in the city at a time of mounting confrontation between Islamists and the military-backed government.

The attacks fueled fears of an increasing militant insurgency in retaliation for the military's July 3 ouster of Islamist President Mohammed Morsi and the subsequent crackdown on his Muslim Brotherhood and other Islamists.
