‘Commercial scale’ oil smuggling into Turkey becomes priority target of anti-ISIS strikes

Islamic State’s daring and impudent oil smuggling into Turkey should become a high-priority target in order to cripple the terrorist group, President Putin said, backed by French President Francois Hollande. Both agree that the source of terrorist financing must be hit first and foremost.

Commercial-scale oil smuggling from Islamic State controlled territory into Turkey must be stopped, Putin said after meeting Hollande in Moscow.

“Vehicles, carrying oil, lined up in a chain going beyond the horizon,” said Putin, reminding the press that the scale of the issue was discussed at the G20 summit in Antalya earlier this month, where the Russian leader demonstrated reconnaissance footage taken by Russian pilots.
