At least 33 Turkish soldiers have been killed in an air strike by Syrian “regime forces” in north-western Syria, a senior Turkish official has said.
More were hurt in Idlib province, said the Governor of Turkey’s Hatay province. Other reports put the death toll higher.
Turkey later retaliated against Syrian government targets.
Syrian forces supported by Russia are trying to retake Idlib from rebels who are backed by Turkish soldiers. The Syrian authorities have so far made no public comments on the latest escalation in Idlib, the last Syrian province to remain in opposition hands.
