The Syrian army is determined to end any form of U.S. presence in the country, state television said on Monday, citing an official source in the foreign ministry.
The U.S.-led coalition is working with Syrian militias to set up a new border force of 30,000 personnel. The move has also heightened Turkey's anger over U.S. support for Kurdish-dominated forces in Syria.
The Syrian foreign ministry blasted the U.S.-backed border force as a "blatant assault" on its sovereignty, state media had also said.
The U.S-led coalition in Syria says it has recruited 230 new cadets for the border security force it's establishing together with the Syrian Kurdish-led opposition fighters to secure areas recently liberated from Islamic State militants.
The force will be tasked with securing Syria's northern border with Turkey and the eastern border with Iraq.
