Syria's state news agency on Sunday said the U.S.-led coalition has fired several missiles at Syrian army positions in the country's east, causing material damage.
The Syrian Arab News Agency report said the positions are in the Ghorab Mountains south of the eastern town of Sukhna.
There was no immediate confirmation from the U.S.-led coalition.
Such attacks by the U.S.-led coalition against Syrian troops have been rare. In 2016, U.S.-led warplanes bombed Syrian army positions in the eastern city of Deir ez-Zor and killed dozens of soldiers.
U.S. troops have a base in Tanf, in southern Syria near the Jordanian and Iraqi borders, and U.S. troops are also in the country's north, near the border with Turkey.
