Islamic State says in total control of Syria's Palmyra

BEIRUT (Reuters) - Islamic State is in complete control of the Syrian city of Palmyra, including the military airport and prison, after the "collapse" of pro-government forces there, the militant group said on Thursday in a statement on Twitter. The retreating forces "left behind a large number of (their) dead" which it said filled the city square, the statement said.
