The Syrian regime said on Thursday that an agreement between Ankara and Washington over northeastern Syria represented a "blatant attack" on Damascus's territorial unity and a "dangerous escalation".
The agreement setting up a joint operation center to manage a safe zone at the Turkish border showed "American-Turkish partnership in the aggression against Syria", state news agency SANA cited a foreign ministry source as saying.
The US-Turkish "aggression" represented "a dangerous escalation and a threat to peace and stability in the area," the source added, according to The Associated Press.
Damascus said the planned zone "serves Turkey's expansionist ambitions," accusing both Ankara and Washington of violating its sovereignty.
A senior Syrian Kurdish official welcome the deal.
"This deal may mark the start of a new approach but we still need more details," Aldar Khalil told AFP on Thursday.
"We will evaluate the agreement based on details and facts, not headlines," he noted.
In recent weeks, Turkish media have repeatedly shown images of military convoys heading for the border area, carrying equipment and fighting units.
