An Iranian military base in Syria was attacked on Tuesday, sources confirmed to Fox News.
At least nine people died in the attack, Rami Abdel Rahman, director of the Syrian Observatory for Human Rights in Britain, told AFP. The report could not be independently confirmed by Fox News.
The military compound that was hit is located about 10 miles south of the Syrian capital city of Damascus, western military sources said.
Syrian TV reported that it was an Israeli airstrike and that Syrian air defense systems shot down two missiles.
The attack happened in Kisweh, according to the official news agency SANA, about an hour after President Trump's announced that he would be pulling the U.S. out of the Iran nuclear deal.
High tension between rivals Iran and Israel have prompted an increasing number of strikes as of late. Iran has promised to respond to Israeli-led attacks aimed at Iranian outposts in Syria.
Those include an attack on Syria's T4 air base in the Homs province in April that killed seven Iranian military personnel. And on April 30, Israel was accused of attacking government outposts in northern Syria, which left several pro-government fighters, some of whom were Iranians, dead.
On Tuesday, the Israeli military said they'd identified "irregular activity of Iranian forces in Syria" and urged citizens in Golan Heights near Syria to ready bomb shelters.
