Anatoly Antonov, the defence minister, said Turkish leaders 'would not acknowledge anything - even if their faces are smeared with the stolen oil'

He accused the Turkish president's family of benefiting from the oil trade

Russia has today accused the Turkish president's family of involvement in the illegal oil trade with ISIS - part of a black market enterprise which adds millions of dollars to the terrorists' coffers.

Speaking to reporters in Moscow, defence minister Anatoly Antonov sensationally revealed satellite images which, he claimed, showed tanker trucks freely crossing the Syrian border into Turkey.

Mr Antonov also said Russia had seen evidence that Recep Tayyip Erdogan and his family are linked to ISIS oil.

His comments come as both countries refuse to back down in an escalating war of words following the Turkish army's downing of a Russian jet it claims breached its airspace last week.

Antonov said today: 'President Erdogan and his family are involved in this criminal business.

'We know the price of Erdogan's words. Turkish leaders won't step down and they won't acknowledge anything even if their faces are smeared with the stolen oil.'

To accompany his comments, his ministry released what it claimed was surveillance footage showing dozen of trucks crossing into Turkey.

The defence ministry officials showed the journalists what they said were satellite images depicting thousands of trucks carrying oil from ISIS-occupied areas in Syria and Iraq into Turkey.

They did not, however, provide any evidence to back up the claims of personal involvement of Mr Erdogan and his family in the illegal oil trade.

Antonov claimed that ISIS militants make £1.33billion a year from the illegal oil trade.

Lieutenant General Sergei Rudskoi, of the Russian military's general staff, also claimed Russian airstrikes on the ISIS oil infrastructure in Syria had halved the militants' profits.

The Turkish president has denied Turkey's involvement in oil trade with the ISIS, and said repeatedly that he would resign if Russia proves its accusations.

Last week, speaking in Ankara, he said: 'They claim Turkey is buying oil from Daesh' - using the Arabic acronym for ISIS.

'Shame on you. Those who claim we buy oil from Daesh are obliged to prove it. If not, you are a slanderer.'
