ISIS gunman kills two US service members, one interpreter killed in Syria

Fox News' Lucas Tomlinson provides details on U.S. Central Command's announcement that three were killed and three injured during an ambush by an ISIS gunman in Syria.

President Donald Trump warned Saturday that there will be "very serious retaliation" after a lone Islamic State gunman in Syria killed two U.S. Army soldiers and a U.S. interpreter in an ambush attack.

Chief Pentagon spokesperson Sean Parnell announced earlier that the soldiers and interpreter were targeted in the central Syrian town of Palmyra in an attack that left three others wounded. U.S. Central Command said the deaths and injuries were a "result of an ambush by a lone ISIS gunman in Syria."

"We mourn the loss of three Great American Patriots in Syria, two soldiers, and one Civilian Interpreter. Likewise, we pray for the three injured soldiers who, it has just been confirmed, are doing well. This was an ISIS attack against the U.S., and Syria, in a very dangerous part of Syria, that is not fully controlled by them," Trump wrote on Truth Social. 

"The President of Syria, Ahmed al-Sharaa, is extremely angry and disturbed by this attack. There will be very serious retaliation," he added.

In comments to reporters outside of the White House on Saturday, Trump also said, "This was an ISIS attack on us and Syria. And again, we mourn the loss and we pray for them and their parents and their loved ones."

Parnell wrote on X that the attack happened as the soldiers "were conducting a key leader engagement."

"Their mission was in support of ongoing counter-ISIS/counter-terrorism operations in the region," he added, noting that "The soldiers’ names, as well as identifying information about their units, are being withheld until 24 hours after the next of kin notification. "

Secretary of War Pete Hegseth said that, "The savage who perpetrated this attack was killed by partner forces."

"Let it be known, if you target Americans — anywhere in the world — you will spend the rest of your brief, anxious life knowing the United States will hunt you, find you, and ruthlessly kill you," Hegseth also said in a post on X.

Parnell said the attack is currently under investigation. A Pentagon official told Fox News Digital that the attack unfolded in a place where the Syrian President Ahmed al-Sharaa does not have control.

"I’m praying for the brave U.S. soldiers and civilian who lost their lives, those who were injured in this attack, and the families who bear this profound loss," Army Secretary Daniel Driscoll wrote on X. "The men and women who serve our country represent the very best of our nation. We mourn the passing of these heroes and honor their service and sacrifice."

A senior U.S. official earlier confirmed to Fox News there were multiple injuries after American service members were ambushed in Syria.

"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.

The injured in Saturday's attack were taken by helicopters to the al-Tanf garrison, which is near the border with Iraq and Jordan, The Associated Press reported, citing Syrian state media.

There are currently around 900 U.S. troops in Syria.

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.
