The commandant of the U.S. Marine Corps says he is gravely concerned by reports that Marines in Iraq may have killed as many as 24 unarmed civilians in Haditha last year.
In a press conference Wednesday at the Pentagon, General Michael Hagee vowed that anyone found to have violated rules and regulations will be held accountable.
The general, just back from Iraq, did not provide details of the Pentagon's investigation into what happened in Haditha.
Meanwhile, Iraqi authorities freed nearly 600 prisoners, after Prime Minister Nouri al-Maliki promised to release 25-hundred detainees to promote national reconciliation.
Most of those released are members of Iraq's minority Sunni Arab community. Authorities say they were not involved in violent crimes or had been detained by mistake.
In violence today, insurgents killed at least 10 people in attacks across Iraq. The dead included six police officers and a Sunni Arab cleric.
Police also say they found alive at least 13 of the 50 men kidnapped in Baghdad on Monday. Police say some of them appear to have been tortured. There was no immediate word on the fate of the other kidnapped victims or why they were taken.
And CBS News correspondent Kimberly Dozier arrived back in the United States after being seriously wounded in a roadside bombing last week in Baghdad. The blast killed two members of a CBS News crew.
News reports say Dozier is being taken to a U.S. Navy military hospital near Washington for further medical treatment.
