Thirty-five soldiers injured in the attack have been evacuated to hospitals in Turkey, Dogan said.
A security meeting is being held at the presidential palace after the “nefarious attack against heroic soldiers in Idlib who were there to ensure our national security,” according to a statement from Turkish director of communications Fahrettin Altun.
Turkey has retaliated in an effort to “revenge our martyred heroic soldiers,” the statement said.
Turkish Foreign Minister Mevlut Cavusoglu spoke to NATO Secretary General Jens Stoltenberg following the Syrian attack, according to a statement released by the ministry. There were no further details about the content of the call.
The Syrian government has not commented on the Turkish claim. The Russian Defense Ministry denied that its air force carried out strikes in the area of Idlib where the Turkish soldiers were located. Moscow said Turkish forces were “located near the areas where terrorist groups were situated” and then “came under fire from Syrian forces.”
Turkish soldiers are in the last rebel-held area of Syria as part of a 2018 de-escalation agreement between Ankara and Moscow. The Syrian government, backed by Russia, has mounted an aggressive air campaign against rebels in Idlib in recent weeks.
Tens of thousands are still on the move, and nearly 700,000 of the displaced are women and children, the UN said.
A spokesperson for the State Department said the United States is “very concerned.”
“We are in contact with Turkish authorities to confirm these developments and to have more clarity on the current situation on the ground,” the spokesperson said.
“We stand by our NATO Ally Turkey and continue to call for an immediate end to this despicable offensive by the Assad regime, Russia and Iranian-backed forces.”
