Russian President Vladimir Putin on Thursday threatened further sanctions against Turkey for the downing of a Russian warplane.
Warning that Turkey will regret many times for shooting down a Su-24 on the Syrian-Turkish border last week, Putin claimed that Russia is aware of Ankara's illegal oil trade with the Islamic State (IS) terrorist group.
"We know who in Turkey is filling their pockets and allowing terrorists to profit from oil robbed from Syria. It is with this money that the bandits hire mercenaries, buy arms and organize inhuman attacks against our citizens," Putin told the Federal Assembly in his annual state of the union address.
Ties between Moscow and Ankara have worsened dramatically since the downing of the plane, which Turkey claimed violated its air space. Russia denied the charge.
In the attack, a Russian pilot onboard the jet was killed. A marine was killed in the following rescue operation.
Putin's address started with a moment of silence to mourn the deceased soldiers, whose wives were also present.
Meanwhile, Putin stressed that Russia considers the Turkish people friendly and Moscow has no intention to engage in saber-rattling with Ankara over the downing of the Russian jet.
Russia has slapped a set of sanction measures on Turkey involving bans on agricultural products and construction companies in response to Ankara's refusal to apologize for the incident.
Putin threatened in his speech with further sanctions.
The Russian leader also called for a unified anti-terror front under the framework of the United Nations, saying that it was impossible to secure any victory over terrorism by efforts of a single country amid open borders and a huge flow of refugees.
