BAGHDAD (AP) - An Iraqi security official says 13 people were killed overnight in a village west of Baghdad.
Maj. Gen. Qassim al-Moussawi, head of Baghdad's Operations Command, said in a statement that officials are looking into the 13 deaths and suspect it may have been a tribal dispute.
Mohammed Sadoun, an official who works at Abu-Ghraib hospital where the bodies were taken, told The Associated Press on Monday that at least seven bullet-riddled corpses were brought to the hospital in the morning.
Violence in Iraq has fallen off dramatically since the height of the sectarian tensions in 2006 and 2007. But such killings like those near Abu Ghraib raise concerns that violence may return.
