BEIRUT (AP) - Syria's dominant Kurdish party on Wednesday called on the U.N. Security Council to act quickly to ensure the safety of Kurdish-controlled territories in the country's north, including an enclave that Turkey has threatened to attack.
Turkish President Recep Tayyip Erdogan has said he will launch a military offensive in the coming days against territories controlled by the dominant Syrian Kurdish militia in northwestern and eastern Syria, and in particular the enclave of Afrin, where an estimated 1 million people live.
Turkey views the U.S.-backed Syrian Kurdish forces as terrorists, and an extension of the Kurdish insurgency raging in its southeast. It has criticized the U.S. for extending support and arming the Kurdish forces as part of the campaign that drove the Islamic State group from large parts of Syria.
The Kurdish militia, which forms the backbone of the U.S.-backed Syrian Democratic Forces, now controls nearly 25 percent of Syrian territory. It is the U.S.-led coalition's chief ally in the campaign against IS militants in Syria.
The U.S.-led coalition recently said it is planning a 30,000-strong Kurdish-led border force, further angering Turkey.
"Turkey has reached the end of its patience," Turkish Deputy Prime Minister Bekir Bozdag said Wednesday after a Cabinet meeting. "No one should expect it to show more patience. Turkey is determined to take whatever steps are necessary."
Turkey's National Security Council also met Wednesday and vowed to take steps to "eliminate" threats from western Syria - in an apparent reference to Afrin.
A statement issued at the end of the meeting also criticized the United States, saying Turkey was saddened by the fact an ally has "declared terrorists as partners" and "armed them without taking our security into consideration." It called on the U.S. to reclaim all arms supplied to Syrian Kurdish fighters.
In reference to the planned Kurdish-led border force, the statement added: "Turkey will not allow the creation of a terror corridor or an army of terror near its border."
Turkish Foreign Minister Mevlut Cavusoglu said he told U.S. Secretary of State Rex Tillerson that those plans were a "perilous" step that would "seriously endanger ties." The two met Tuesday in Vancouver.
In a speech at Sanford University on Wednesday, Tillerson said the U.S. government "hears and takes seriously the concerns of our NATO ally Turkey."
"We recognize the humanitarian contributions and military sacrifices Turkey has made towards defeating ISIS, towards their support of millions of Syrian refugees, and stabilizing areas of Syria it has helped liberate," he added. "We must have Turkey's close cooperation in achieving a new future for Syria that ensures security for Syria's neighbors."
Erdogan said the imminent military operation is to "purge terror" from near its borders. Along with Afrin, Erdogan has also threatened Manbij, a town the Kurdish-led SDF seized from IS in 2016.
The Kurdish Democratic Union Party, or PYD, the political arm of the main Kurdish militia, said that if Turkey launches an operation against Afrin, the world will bear responsibility for the lives of people residing there. The PYD called on the Security Council to "move immediately" to ensure the security of Kurdish-controlled areas in Syria.
"Such a responsible behavior will lead to the desired result in finding a resolution for the Syrian crisis," the PYD said in a statement.
The Syrian government of President Bashar Assad has meanwhile accused the SDF of being "traitors" for cooperating with the United States.
