The U.S. troops who were killed and injured in Saturday’s ambush attack in Syria were members of the Iowa National Guard, a senior U.S. official told Fox News.
An ISIS gunman opened fire with an automatic weapon in the central Syrian town of Palmyra, killing two Iowa National Guard soldiers and an American civilian translator, the official said.
Three additional U.S. soldiers were wounded in the attack.

Preliminary information suggests the attacker was once affiliated with the Syrian government forces and had been a low-level member of the Syrian Security Forces, before later becoming connected to ISIS, the official said.
“He was not a part of the official delegation that was being escorted by the US and Syrian troops,” the official said. “… This would not be considered a ‘green on blue’ incident because the Syrian gunman was not part of the US/Syrian partnered delegation.”
