Syrian who killed Americans was part of security forces, interior ministry says

Syria's interior ministry said Sunday the gunman who killed three Americans in the central Palmyra region the previous day was a member of the security forces who was to have been fired for extremism. Two US troops and a civilian interpreter died in what the Syrian government described as a "terrorist attack" on Saturday, while Washington said it had been carried out by an Islamic State group (IS) militant who was then killed.
