Airports of Turkey, Balkan and Eastern European states, as well as of Switzerland, are the main points through which the Islamic State terrorists return to their home countries, Andrey Novikov, the head of the Commonwealth of Independent States Anti-Terrorism Center, told Sputnik.
"The majority of terrorists will return to their origin countries, or go to other states (both CIS and the European Union) via the routes they used to leave for conflict zones. In practice, this means using connecting flights from Turkey to airports of Commonwealth’s [CIS] cities. Special research shows that the Balkan route is especially in demand," he said.
According to Novikov, Hungary and Poland are also used as transit countries, as well as Romania and Switzerland to a lesser extent.
