The rift is growing between Russia and Turkey.
The Russian Defence Ministry claims it has proof that Turkey is involved in the trading of oil with ISIL militants.
Officials released satellite pictures, alleging they show oil tankers heading along three roads from ISIL-held areas to Turkey.
Anatoly Antonov, the Deputy Russian Defence Minister, told a news conference: “Turkey is the principal consumer of this oil, stolen from its legitimate owners,Syria and Iraq.
“According to inbound data, top Turkish leadership is involved in this criminal business, including president Erdogan and his family.”
Pro-government media in Turkey dismissed the claims as impossible, saying the roads shown by Russia are controlled by Kurdish rebels and the Syrian army.
President Erdogan also denied the claims.
“Turkey has not lost its moral values; we’re not buying oil from a terrorist organisation,” he said.
“We are watching Russia’s disproportionate reactions with sadness, while the whole world accepts that we are right.
“If Russia’s reactions continue, we will be forced to take our own measures, “ said Erdogan.
