Today, two missiles hit the base where US soldiers are stationed in eastern Syria.
Foreign media report that there was no loss of life or material damage from the attack, the American army announced.
So far, no one has claimed responsibility for the attack, adding that in that part of Syria it is not unusual for bases where US soldiers are stationed to be hit by rockets or mortar attacks.
US Central Command Vice President Joe Buccino said that “attacks of this type put coalition forces and civilian populations at risk and undermine the hard-won stability and security of Syria and the region.”
Central Command said members of the US-backed Kurdish-led Syrian Democratic Forces visited the site from which the missiles were fired and found a third that had not been fired.
The UK-based Syrian Observatory for Human Rights said the missiles were fired from Arab tribes armed by Iran.
There are about 900 US soldiers in Syria, media reports.
