Russia and Turkey have announced a deep demilitarised zone will be established in Syria’s Idlib region, the last bastion of anti-government rebels where fears had been high of a devastating offensive by government forces.
Syrian government and Russian planes have targeted the southern edge of Idlib province with a series of air strikes, activists said.
Donald Trump has warned Syrian president Bashar Assad and his allies against a “reckless attack” on Idlib province.
Syrian opposition fighters have blown up bridges linking areas they control to government-held territories in the north-west in anticipation of a military offensive against their last stronghold in the country.
The UN envoy for Syria has proposed that civilians in the rebel-held region of Idlib could evacuate to government areas.
