Beirut: Turkish drone strikes killed 26 Syrian soldiers in northwestern Syria Saturday, the Syrian Observatory for Human Rights war monitor said.
Earlier in the day, Turkey's President Recep Tayyip Erdogan threatened reprisals for the killing of dozens of Turkish troops in Syria on Thursday.
"Twenty-six members of the Syrian army were killed when Turkish drones targeted positions of the regime forces in the Idlib and Aleppo countryside," the Britain-based Observatory said.
The apparent retaliation came after 33 Turkish soldiers were killed in an air strike by Syrian regime forces on Thursday. A 34th soldier later died from his injuries.
Russia-backed regime forces have since December led a military offensive against the last major rebel stronghold of Idlib in northwestern Syria, where Turkey supports some rebel groups.
