The US special envoy on International Energy, Amos Hokstayn, has confirmed instances of Daesh smuggling oil to Turkey. However, in his opinion, the amount of oil that reaches the territory of Turkey is negligible.
"The volume of the contraband oil is extremely small, it is decreasing with time and is insignificant from a quantitative point of view," he said.
According to the State Department, a standard tanker can hold 200-250 barrels of oil. According to the State Department, it is necessary to carry at least 1000 oil tankers for it to really matter to the Turkish economy, Interfax reports.
