Two U.S. Army soldiers and a civilian U.S. interpreter were killed Saturday in an attack near Palmyra, Syria, the Pentagon confirmed. The incident resulted in three other U.S. personnel sustaining injuries.

The attack occurred in the Palmyra region, a historically significant area containing ancient Roman ruins that have been repeatedly targeted and controlled by various factions throughout the Syrian civil war. Palmyra’s strategic location has made it a point of contention in the ongoing conflict.

Details surrounding the attack remain limited, but the Pentagon stated that it is currently under investigation. No group has yet claimed responsibility for the assault. The identities of the deceased soldiers and the interpreter are being withheld pending notification of next of kin.

The U.S. military maintains a presence in Syria as part of the ongoing effort to combat remnants of ISIS and stabilize the region. U.S. forces work alongside Syrian Democratic Forces (SDF) partners in this mission. This latest incident underscores the continued risks faced by U.S. personnel operating in Syria.

The three wounded U.S. personnel are reportedly receiving medical attention. Further updates will be provided as they become available from the Department of Defense.
