Los Angeles ? All charges have been dismissed against two Marines accused in the killings of 24 Iraqi civilians in Haditha, the Marine Corps announced Thursday.

Lance Cpl. Justin L. Sharratt, 22, of Canonsburg, Pa., was charged with murdering three brothers. Capt. Randy Stone, 35, a battalion lawyer from Dunkirk, Md., was charged with failing to adequately report and investigate the Nov. 19, 2005, combat action in which women and children were among the dead.

In his decision to dismiss charges, Lt. Gen. James Mattis, the commanding general with jurisdiction in the case, said he was sympathetic to the challenges Marines on the ground face in Iraq.

The decision to drop charges against the two Marines follows earlier recommendations by investigating officers who listened to evidence against them, though it was recommended that Stone face an administrative hearing.
