Sunni Arab groups in Iraq are blaming Shi'ite-led security forces for the killing of 14 Sunni Arab men whose bodies were found Friday in Baghdad.
The Sunni Arab groups say Interior Ministry forces picked up the 14 men at a Baghdad mosque last month.
Major-General Hussein Ali Kamal of the Interior Ministry told the Associated Press that officials are investigating reports that the men were detained by government forces.
The discovery of the bodies threatens to further polarize Iraq's Sunni Arab, Kurdish and majority Shi'ite communities. Politicians from the three groups are holding talks on forming a national unity government following the elections in December.
The United States is hoping the formation of a unity government will help curb the insurgency in Iraq. Some information for this report was provided by AFP and AP.
