An attack by an alleged Islamic State member in Syria has killed two U.S. service members and one American civilian.

The gunman who killed two U.S. soldiers and an American civilian interpreter had been set to be dismissed from the security forces over his extremist views, U.S. and Syrian officials said.

Two U.S. service members were killed in an ambush near Palmyra in Syria, the first attack to inflict casualties since the fall of President Bashar Assad.

The attack on U.S. troops in Syria is the first to inflict casualties since the fall of President Bashar Assad a year ago.

The killing of three Americans during what was said to be a counterterrorism operation in central Syria served as a reminder that U.S. troops are still operating in the country.

President Trump said Saturday that 'we will retaliate' after two U.S. service members and one American civilian were killed in a Syria attack that the U.S. blames on the Islamic State group.

A smooth integration of the Kurdish-led Syrian Democratic Forces could build a stronger, more professional Syrian military capable of providing security throughout Syria.

I want to just pay my respects to the people, unfortunately, two are no longer with us, Brown University, nine injured, and two are looking down on us right now from Heaven,” Trump said via the New York Post.
