Two U.S. soldiers and an interpreter were killed in an ambush by an apparent ISIS gunman in Syria Saturday, officials said.

Two U.S. Army soldiers and a civilian interpreter were killed in Syria on Saturday by a suspected Islamic State attacker who targeted a convoy of American and Syrian forces before being shot dead, the U.

President Trump said in a Truth Social post that it was an "ISIS attack against the U.S." and Syria and that there will be "very serious retaliation."

Three U.S. military personnel — two army soldiers and a civilian interpreter — were killed on Saturday after an attacker targeted a convoy of American and Syrian forces, the U.S. military said.

Two soldiers and a civilian interpreter were killed while supporting counterterror operations, the Pentagon said. They are the first U.S. casualties in Syria since the fall of the dictator Bashar al-Assad.

Syria’s state news agency said two Syrian military personnel were also injured in the attack. Tom Barrack, U.S. ambassador to Turkey and the Trump Administration’s special envoy to Syria, also condemned the attack and paid tribute to the soldiers.

Three other service members were injured in the attack, during which the gunman was "engaged and killed", according to the US military.

Since the fall of Syrian dictator Bashar al-Assad last December, the Trump administration has embraced the new Syrian leader, Ahmed al-Sharaa, who has ties to Al Qaida. The Islamic State, which the U.S. declared in 2019 was mostly defeated, has remained a threat in Syria and has continued to conduct attacks since Assad’s departure.
