BEIRUT - Syria's main opposition group on Wednesday condemned the US-led coalition's plan to create a 30,000-strong border force on the war-torn country's northern frontier with Turkey.
The alliance fighting the Islamic State (IS) group announced on Sunday that it was working with Arab and Kurdish fighters from the Syrian Democratic Forces (SDF) to establish a Border Security Force.
The proposed force has been denounced by Damascus, while Turkey -- which considers the Kurdish People's Protection Units (YPG) "terrorists" -- has vowed to nip it "in the bud".
The exiled Syrian National Council opposition group, in a statement, condemned the "US plan for a border force" and said "it was unacceptable" for areas liberated from IS to fall under Kurdish control.
The Kurds have sought to remain neutral in Syria's nearly seven-year-old war between rebels and the government.
With US backing, the YPG, the main element of the SDF, has seized swathes of territory in northern and eastern Syria from IS and established semi-autonomous rule in those areas.
The US-led coalition insists the border force would be responsible for stopping a resurgence of IS.
The YPG head on Tuesday hit out at threats by Turkish President Recep Tayyip Erdogan to attack his forces.
Ankara accuses the YPG of being a branch of the outlawed Kurdistan Workers' Party (PKK) that has waged an insurgency in Turkey since 1984.
