BAGHDAD (Reuters) - Residents of a town north of Baghdad found 12 corpses with execution-style bullet wounds on Monday following fighting between rival Sunni insurgents that could eventually unravel a coalition which has seized much of northern and western Iraq.
The incident points to an intensification of infighting between the Islamic State and other Sunni groups, such as supporters of former dictator Saddam Hussein, which rallied behind the al Qaeda offshoot last month because of shared hatred for the Shi'ite-led Iraqi government.
