AlHijjah 16, 1434, Oct 21, 2013, SPA -- A coordinated attack Monday against police headquarters in central Iraq killed seven policemen, officials said, according to AP. The attack in the city of Fallujah, 65 kilometers (40 miles) west of Baghdad, involved at least two suicide bombers and several gunmen, a police official said. One bomber detonated his explosives-laden belt at the main checkpoint outside the Fallujah police headquarters, while the second blew himself up near the building gates as security forces engaged in a shootout with other gunmen, the official said. Later, the gunmen fled to an electricity department building nearby, taking two policemen and two guards hostage, he added. That prompted sporadic clashes with security forces. A few hours later, the four were freed, two militants were killed and three attackers were arrested.
