US military vehicles patrolled the streets of Palmyra, Syria, and warplanes launched light bombs into the sky over the city between 8:16 PM and 8:46 PM UTC on December 13, 2025, as reports indicated an ongoing US ground operation targeting alleged ISIS cells, according to NAYA reports and an X post by Worldsource24. NAYA published images of American military vehicles moving through Palmyra streets and additional scenes of US warplanes releasing light bombs overhead during the 30-minute window. The X post from Worldsource24 described the ground operation as ongoing and aimed at ISIS cells in the Syrian city. The activity follows US military patrols in Palmyra reported earlier between 7:46 PM and 8:15 PM UTC, as noted by NAYA, amid counter-ISIS operations in the area where an ISIS gunman ambushed a US-led coalition delegation earlier on December 13, killing two US service members, one US civilian, and wounding three, according to US Central Command.
