Russia has rejected the allegations that its use of Iranian military bases for air strikes in Syria violates United Nations sanctions on Tehran.

Russian Foreign Minister Sergey Lavrov said in Moscow that Russian Air Force uses its fighter jets to take part in the counter-terrorism operation in Syria and there has been no supply, sale or transfer of fighter jets to Iran. His statement comes following allegations by US State Department spokesman that Russia’s operation out of Iran could violate the UN resolution that prohibits supply, sale and transfer of combat aircraft to Iran unless approved by the Security Council.
