EDS NOTE: GRAPHIC CONTENT - FILE - In this Thursday, May 9, 2013 file photo, bodies of killed militants lie on a highway at Gubden, in Russian republic of Dagestan. The leader of a restive province in Russia's Caucasus Mountains said that local Islamic militants are fighting alongside Syrian rebels and could further destabilize their home region when they come back. Ramazan Abdulatipov, the acting president of the province of Dagestan, urged local authorities on Sunday, July 21, 2013 to prevent the "export of extremists," and make it hard for militants to leave Russia.
