ISTANBUL — Turkish President Recep Tayyip Erdogan warned the last rebel stronghold of Idlib in northwest Syria was on the verge of destruction as a barrage of airstrikes have killed hundreds of civilians since April and another tentative cease-fire is tested by lethal clashes.
Erdogan is the most outspoken supporter of the remnants of an opposition battling President Bashar al-Assad’s forces in the eight-year war, yet has also worked closely with Assad’s main backers, Russia and Iran, in a series of efforts to forestall an all-out attack on Idlib, a province adjoining Turkey where some three million people live.
