Turkish-backed Syrian rebels pledged on Friday to back a potential cross-border offensive that Ankara has threatened to mount against Kurdish fighters in northeast Syria, according to Reuters.
Ankara and Washington have agreed to set up a zone in northeast Syria along the border with Turkey, which wants to expel the Syrian Kurdish People’s Protection Units (YPG) militia from the frontier.
Turkey has accused the United States, which helped the YPG defeat Islamic State in Iraq and the Levant (ISIL) militants, of moving too slowly to establish the zone. The two countries are also at odds over how far it should extend into Syria and who should control it.
Turkey wants the zone to go 30 km (19 miles) inside Syria and has repeatedly warned it could launch its own operation.
President Recep Tayyip Erdoğan said on Tuesday that given the lack of progress Turkey had no choice but to act alone — his most direct indication yet of a military incursion.
US support for YPG fighters has infuriated Ankara, which sees them as linked to the Kurdish PKK movement that has waged a decades-long insurgency inside Turkey.
“When it comes to the east of the Euphrates (river) … it is our duty to fight,” Salim İdris, an official of the Turkey-backed Syrian opposition, told a news conference in southeast Turkey.
“We stand in full force in support of our Turkish brothers in fighting all forms of terrorism represented by the PKK gangs.”
With ties between the NATO allies already under strain, diplomats and analysts say Erdogan would be unwilling to anger Washington with a full-scale incursion into northeast Syria, where US forces are stationed alongside the YPG.
But Turkey, which has twice launched military offensives with its insurgent allies in northern Syria in recent years, has been pressing for more efforts to set up the border zone.
Turkey, which backs insurgents holding tracts of territory in northwest Syria near its border, also has about a dozen military posts in the nearby Idlib region.
