ISTANBUL — Turkey is intensifying diplomatic efforts with Russia to deescalate violence in the northwest Syrian province of Idlib, its foreign minister said Wednesday, as it seeks to stave off an all-out assault on the opposition’s last stronghold that could spark a humanitarian disaster.
Moscow and Ankara support opposing sides in Syria’s eight-year conflict but have worked together to move the warring parties toward a political resolution. Their efforts include agreeing to a demilitarized zone last year for Idlib, which is controlled by militias fighting President Bashar al-Assad’s forces and where more than 3 million civilians are sheltering from the war.
