Turkey shot down Russia's bomber as revenge for the destruction of oil smuggling business that belongs to Recep Tayyip Erdogan's son, a Syrian minister stated.

DAMASCUS (Sputnik) – Turkey downed the Russian Su-24 Fencer bomber over Syria in response to the destruction of hundreds of semi-truck oil tankers sent to Turkey from Syria by the Islamic State, Syrian Information Minister Omran al-Zoubi said.

The information minister said that oil smuggled into Turkey was bought by the Turkish president’s son, who owns an oil company.

“All of the oil was delivered to a company that belongs to the son of Recep [Tayyip] Erdogan. This is why Turkey became anxious when Russia began delivering airstrikes against the IS infrastructure and destroyed more than 500 trucks with oil already. This really got on Erdogan and his company’s nerves. They’re importing not only oil, but wheat and historic artefacts as well,” al-Zoubi told RIA Novosti in an interview.

“The fact of the attack on the [Russian] plane in Syrian airspace without any warning, as the surviving Russian [co-]pilot reported, confirms once again that Turkey is lying,” the information minister said.

On Tuesday, a Turkish Air Force F-16 downed the Russian bomber 4 kilometers from the Turkish border. Both the Russian General Staff and the Syrian Air Defense Command confirmed that the Su-24 never crossed into Turkish airspace and was shot down over Syrian territory, citing precise objective control data.

Russian President Vladimir Putin described the incident as a "stab in the back, carried out against us by accomplices of terrorists."

One of the two Su-24 pilots was killed by fire from the ground after ejecting from the plane. The second pilot was rescued in a 12-hour-long operation.

Russia has been carrying out an aerial campaign against the Islamic State jihadist group in Syria since late September at the request of Damascus. Moscow has repeatedly called on the UN Security Council to take extra steps to determine who was buying oil from the militants.

Syria has repeatedly accused Turkey, as well as several Gulf states, of funding ISIL.
