Syrian President Bashar al-Assad also vowed to crush the new border force and drive us troops from Syria, while Russian Federation charged that the plan showed the United States intends to partition Syria by allowing Kurdish forces to consolidate their hold on the approximately 25 percent of Syrian territory they now control after liberating it from IS. The Kurds were Washington's most trusted force in the USA -led campaign to drive Islamic State extremists from Syria, but Turkey's government says they work hand-in-hand with PKK militants who have been battling for autonomy in Turkey's southeast since the 1980s.
The PYD/PKK is the Syrian offshoot of the PKK terrorist group, which has been designated a terrorist organization by Turkey, the US and the EU.
However, US Secretary of State Rex Tillerson said on Wednesday that Washington owed Turkey an explanation over the reports on the border force plans, adding that the issue has been "misportrayed". "The U.S. must stop cooperating with this terrorist organization", he said of the Kurdish fighters.
"The countdown has begun for Turkey's operation against Afrin", said one pro-government channel.
The new Syrian Border Security Force (BSF) is now being trained by a joint effort between the Syrian Democratic Forces (SDF) and the Combined Joint Task Force - Operation Inherent Resolve (CJTF-OIR), established and led by the United States to destroy the Islamic State (IS).
Officials won't say whether Canada will help with the new border force in Syria - or if it even agrees with the initiative - despite repeated requests for comment. A spokesman for the Kurdish militias that control the district said they had blocked the Turkish army-led initial attempt at a ground incursion on Sunday morning.
The Syrian government has also indicated that it would shoot down any Turkish planes entering its skies.
The Turkish General Staff declared the launch of the operation dubbed Olive Branch against the Kurdish forces in Afrin on Saturday.
"Turkey is obliged to ensure safety of its citizens and borders", Canikli said.
"The Arab Republic of Egypt expresses its rejection of the military operation carried out by the Turkish troops against the town of Afrin in northwestern Syria, considering the operation as yet another violation of Syria's sovereignty and the disruption of efforts within the framework of the existing political decisions and efforts on struggle against terrorism in Syria", the statement said.
"Today the people are protesting to assure that Afrin will never fall into the Turkish traitors' hands", said a female protester.
The Kurdish militia, which forms the backbone of the USA -backed Syrian Democratic Forces, now controls almost 25 percent of Syrian territory.
The MGK statement again slammed the U.S. support for the YPG - an ally of Washington in the fight against Islamic State (IS) jihadists - saying it was "regrettable" that a North Atlantic Treaty Organisation ally had "declared terrorists as a partner". The regime accused Ankara of potentially preparing for a cross-border campaign against Kurdish forces in the restive region.
Bozdag reiterated Ankara's demand that Washington cease its "inexplicable" and "unacceptable" support of the YPG. It also highlighted the "provocative steps" taken by the United States was the main factor contributing to the development of the crisis situation in northwest Syria. He explained that the USA was not creating a new force. "When will this happen?"
