Russian Foreign Minister Sergei Lavrov said Wednesday that the Takfiri group operating in Iraq and Syria, ISIL was Moscow's greatest enemy, notwithstanding the strained relations with the United States over the Ukraine conflict.

"I believe ISIL is our greatest enemy right now," Lavrov said in an interview with Russian radio stations when asked whether he considers China, ISIL or NATO Russia's greatest threat.

Lavrov said "hundreds of Russian citizens, hundreds of Europeans, hundreds of Americans are fighting for ISIL, along with CIS (former Soviet) countries."

"They are already returning home. They come here to rest after fighting and can get up to dirty tricks at home," he said.

"As far as (relations with the) United States are concerned, these are state issues, these are issues of the world order, which have to be resolved through talks."

Russia's relations with the West, particularly with the United States, have plummeted to a post-Cold War low over the war in Ukraine.
