Damascus : Damascus said on Thursday it strongly rejects a proposed US-Turkish buffer zone for northern Syria, blaming the “aggressive” project on Syria’s Kurds, who gave the proposal a guarded welcome. Turkish and US officials agreed on Wednesday to establish a joint operations centre to oversee the creation of a safe zone to manage tensions between Ankara and US-backed Kurdish forces in Syria. No details were provided on the size or nature of the safe zone, but the deal appeared to provide some breathing room after Turkey had threatened an imminent attack on the Kurdish People’s Protection Units (YPG), which control a large swathe of northern Syria. “Syria categorically and clearly rejects the agreement between the American and Turkish occupiers on the establishment of a so-called safe zone” in northern Syria, a foreign ministry source told state news agency SANA.“Syria’s Kurds who have accepted to become a tool in this aggressive US-Turkish project bear a historical responsibility,” the source added, urging Kurdish groups to return to the fold.Turkey has already carried out two cross-border offensives into Syria in 2016 and 2018, the second of which saw it and allied Syrian rebels overrun the Kurdish enclave of Afrin in the northwest. The deployment of Turkish troops and their proxies in Afrin has drawn accusations of a Turkish military occupation.Damascus said the planned buffer zone further east serves “Turkey’s expansionist ambitions,” accusing both Ankara and Washington of violating its sovereignty. A senior Syrian Kurdish official gave the Turkish-US agreement a guarded welcome.“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.” Turkey’s foreign minister on Thursday said the deal was “a very good start”. But Mevlut Cavusoglu said his country would not allow the agreement to turn into a “delaying manoeuvre”. “The accord must be implemented,” he said at a press conference in Ankara, without giving a specific timeline. Wednesday’s deal describes the planned safe zone as a “peace corridor” that can “ensure that our Syrian brothers will be able to return to their country”.
