FILE - In this Dec. 16, 2012 file photo, Free Syrian Army fighters remove the body of a Syrian Army Soldier after heavy clashes with government forces at a military academy besieged by the rebels, in Tal Sheer, Syria. Syrian rebels are killing captured regime fighters and suspected informers with impunity, human rights groups say, pointing to mounting war crimes committed by those trying to topple President Bashar Assad.
