A Turkish soldier was killed on Friday in Syria's Idlib region after an attack on an armoured ambulance, the defence ministry said. Two other soldiers were injured, it said in a statement, adding the army retaliated by hitting specified targets. The ministry did not give further information. A Russian-backed Damascus offensive on the last rebel bastion in the country has killed hundreds of civilians since December and displaced close to a million people. A ceasefire between rebel-backer Turkey and regime-ally Russia was agreed for Idlib and came into force on March 6. Late last month, a Turkish soldier was killed by a roadside bomb while on patrol on the key M4 highway in Idlib. raz/pvh
