MOSCOW, Feb 15 (Reuters) - A Turkish delegation will visit Russia on Monday to discuss the situation in Idlib in northwestern Syria, the TASS news agency reported, after a recent spike in violence in the region.

Turkey and Russia, which back opposing sides in the conflict, agreed in 2018 to set up a de-escalation zone in Idlib but a Syrian government offensive has disrupted this fragile cooperation in recent weeks. (Writing by Polina Ivanova Editing by Frances Kerry)
