During his State of the Nation Address on Thursday, Russian President Vladimir Putin took another dig at Turkey, claiming that Allah punished Turkey's leaders by making them lose their minds, the Express reported.

The war of words between the two countries exploded after Turkey shot down a Russian warplane flying near the Syrian border.

"Probably Allah alone knows why they did it,'' Putin said. "And evidently Allah decided to punish the ruling clique in Turkey, by depriving it of any reason or logic."

Putin condemned the bombing of its fighter jet and described it a "stab in the back" carried out by "accomplices of terrorists."

The Russian Su-24 bomber was shot down by Turkish authorities last month after they claimed it violated their airspace for 17 seconds, the report said.

Ankara claimed it repeatedly warned the jet it was in Turkish airspace. However the surviving pilot said he received no such warning while the Kremlin dismissed the claims as "rubbish," insisting the aircraft had stayed in Syrian airspace.

U.S. officials also reportedly confirmed the warplane was inside Syrian airspace when it was downed.

In retaliation for the incident, Moscow imposed sanctions against Turkey by banning imports of Turkish fruit and vegetables, and preventing Russians from going on package holidays to Turkey.

Putin also warned Turkey that Russia intends to adopt further measures against it. "We will remind them not once about what they have done, and they will feel sorry about it more than once."

Moscow also accused Turkey of buying oil from the Islamic State (ISIS). On Wednesday, Deputy Defence Minister Anatoly Antonov charged that Turkish President Recep Tayyip Erdogan and his family had personal ties to the ISIS oil trade.

"President Erdogan and his family are involved in this criminal business,'' Antonov said, the Associated Press reported. "We know the price of Erdogan words... Turkish leaders won't step down and they won't acknowledge anything even if their faces are smeared with the stolen oil.''

Antonov and other Russian officials claimed that ISIS militants make $2 billion per year from the illegal trade, and said Russian airstrikes have cut the terror group's profits in half, IBT reported.

Erdogan has vehemently denied the accusations.

But Russia showed aerial images showing hundreds of oil truck streaming across the Turkish border to support the claims, said the Express.

"We know that Turkey is filling its pocket and allows terrorists to earn money by selling oil stolen from Syria,'' said Putin. "For that money the bandits are recruiting mercenaries, buying weapons and staging cruel terror attacks aimed against our citizens, as well as citizens of France, Lebanon, Mali and other countries."

The Russian leader urged countries not to apply "double standards on terror" or use terrorist groups for their own ends.
