It's been a very bloody few days in Iraq, and this was a particularly fanatical coordinated attack in the city of Ramadi. First, four car bombs detonated, the first three near the Dawlah Kabir Mosque and the last near a security compound. Then two suicide bombers blew themselves up inside the police station. Finally, six gunmen stormed the compound, killing seven police officers before being killed themselves. There are concerns that sectarian violence could take over the country after the U.S. withdrawal, as Ramadi is mostly Sunni and the security forces are dominated by Shiites. On Saturday, more than 50 Shiite pilgrims were killed in a procession in the southern city of Basra, and even Pakistan was engulfed in sectarian attacks, when more than a dozen people—also Shiite pilgrims in a procession—were killed by a bomb in the city of Khanpur. The series of attacks have killed nearly 200 Iraqis in less than a month.
