Bombings Rock Egyptian Capital

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.

The hours after the bombings saw a public backlash against the Brotherhood, which the government accuses of being behind the monthslong wave of bombings and shootings, though it denies any link. Angry residents joined in with security forces in clashes with Brotherhood supporters holding their daily protests in several districts of the capital and multiple cities across the country in violence that left eight dead.
