US military denies American troops in Syria were attacked

A Syrian opposition war monitor and a spokesman for U.S.-backed Syrian fighters say a facility housing American troops in eastern Syria has come under a rocket attack, but the U.S. military denies there was any attack

“There is no truth to the reports that U.S. forces in Syria were attacked by rockets today,” tweeted coalition spokesman Col. Wayne Marotto.

Earlier Sunday, Siyamend Ali, a spokesman for the U.S.-backed and Kurdish-led Syrian Democratic Forces, said two rockets were fired at al-Omar field in Syria’s eastern province of Deir el-Zour without inflicting any casualties. He added that it was not immediately clear where the rockets were fired from.

The Britain-based Syrian Observatory for Human Rights said the rockets were fired from areas controlled by Iran-backed fighters in the area of Mayadeen, also in Deir el-Zour.

Syria's state news agency, SANA, also reported that al-Omar facility was hit with two rockets.

Later Sunday, the Syrian Democratic Forces denied reports that another base housing U.S. troops was hit, saying the sounds of explosions at the facility, known as Conoco, were from training with live ammunition.

Hundreds of U.S. troops are stationed in northeastern Syria, working with the Syrian Democratic Forces to fight against the Islamic State group.

Thousands of Iran-backed militiamen from around the Middle East are deployed in different parts of Syria, many of them in areas along the border with Iraq.

Iran-backed fighters have joined President Bashar Assad’s forces in Syria’s 10-year conflict. Their presence helped tip the balance of power in Assad’s favor
