LIMA, November 18. /TASS/. The Russian aviation in Syria is currently engaged only in missions in the provinces of Idlib and Homs to prevent militants of the Islamic State group from crossing into Syria from Iraq, Russian Foreign Minister Sergei Lavrov said.

"Our aviation and the aviation of Syria work only in the provinces of Idlib and Homs in order to prevent the IS from crossing into Syria from Mosul," he said.

Earlier this week, Western media and officials have repeatedly accused Russia of striking civilian targets in the Syrian province of Aleppo.

Russia’s Defense Ministry has called the reports a "common lie." On Wednesday, ministry spokesman Major-General Igor Konashenkov said Russian aviation have not been delivering any strikes on Aleppo for 29 days already.
