A senior U.S. official confirmed to Fox News there have been multiple injuries after American service members were ambushed in Syria on Saturday.
The official added that some of the injuries were serious.
Two local Syrian officials earlier told Reuters that a convoy of U.S. and Syrian forces fighting the Islamic State terrorist group was targeted while on patrol in the central town of Palmyra.
The Department of War had told Fox News Digital that "we are aware of reports," but added that it had "nothing additional to provide at this time."
"The United States, CIA and military forces are reportedly deeply involved in securing and stabilizing the situation in Syria," Dan Diker, president of the Jerusalem Center for Security and Foreign Affairs, recently told Fox News Digital.

As of June, the U.S. had about 1,500 troops left in Syria following withdrawals and consolidations ordered by the Pentagon, and that number was expected to drop to just several hundred by the end of this year, according to Fox News Chief National Security correspondent Jennifer Griffin.

Griffin reported that the U.S. had eight bases in Syria to keep an eye on ISIS since the U.S. military went in to prevent the terrorist group from setting up a caliphate in 2014, although three of those bases have since been closed down or turned over to the Syrian Democratic Forces.
On Monday, tens of thousands of Syrians flooded the streets of Damascus to mark the first anniversary of the Assad regime’s collapse.
Those celebrations came a year after former Syrian dictator Bashar al-Assad fled the capital as rebel forces swept through the country in a lightning offensive that ended five decades of Assad family rule and opened a new chapter in Syrian history.
