MOSCOW- Russian Foreign Minister Sergei Lavrov said on Wednesday there were no grounds to suggest Russia's decision to fly Syria bombing missions out of Iran violated UN Security Council resolution 2231.
Lavrov said Russian aircraft had been flying out of Iran as a part of the Kremlin's anti-terrorist operation. No aircraft or supplies had been transferred to Tehran, he said.
The UN resolution prohibits the supply, sale and transfer of combat aircraft to Iran. The United States said on Tuesday it was checking whether the Russian flights had violated it.
Russian SU-34 bombers based at Iran's Hamadan air base on Wednesday carried out another wave of strikes on ISIS targets inside Syria for a second day.
