Moscow warplanes conducted 141 missions over the country at the weekend as the Kremlin's Su-34 bombers torpedoed an oil refinery controlled by the depraved terror group.

The latest demolition saw more than 1,000 tankers controlled by ISIS destroyed.

Among the cities pounded by the former Soviets were the capital Damascus, Aleppo, Homs as well as Raqqa - the terror group's stronghold.

Spokesman for the Russian Defence Ministry Igor Konashenkov confirmed the latest bombings in a statement.

He said: "Russian bombers taking off from the Khmeimim airbase flew on combat missions to destroy tanker convoys and oil refineries in the areas of oilfields in the north and east of Syria.

"A major oil depot was destroyed 15 kilometres southwest of the city of Raqqa."
