MOSCOW (Sputnik) – Most Russians heading to Syria to fight on the sides of terrorists transfer through Istanbul, the aide to the head of the National Anti-Terror Committee said Friday.
"The main route is made by international flights to Istanbul. Daesh's 'special services' run a check on new arrivals to become candidates in terrorist ranks, and then they're sent on to Syria," Andrei Przhezdomsky told journalists.
