Staff Sgt Hal Warner and 1st Lt Michael Behenna are accused of the premeditated murder of Ali Mansour Mohammed.

They have also been charged with assault, making a false official statement and obstructing justice.

Military officials did not provide details on how or when Mr Mohamed was killed, but they said he was released from prison in mid-May.

Staff Sgt Warner will face a hearing later this month to determine whether a trial should be held, a US military spokeswoman said.

No date has been set for a hearing for 1st Lt Behenna.

Both men were stationed near Baiji, 180km (120 miles) north of Baghdad.
