A newly surfaced video appears to show a U.S.-made missile hitting a building in Iran adjacent to a girls’ school where local officials say 168 people were killed, experts told ABC News.

The eyewitness video was first posted Sunday morning by the Iranian outlet Mehr News, and then shared online by Trevor Ball, a former U.S. Army Explosive Ordnance Disposal technician, who now works as a researcher with the investigative group Bellingcat.

Ball said in a post on X that the video showed a U.S.-made Tomahawk missile.

ABC News geolocated the video adjacent to the site of the deadly Feb. 28 strike, in which several buildings connected to Iran’s Islamic Revolutionary Guard Corps were destroyed along with a nearby building housing a school for girls.

The missile seen impacting in the video is not hitting the girls’ school but another building in the IRGC complex.

Experts told ABC News the missile has the characteristics of a Tomahawk, which is used by the United States and is not known to be fielded by Iran or Israel.

Sam Lair, a research associate at the James Martin Center for Nonproliferation Studies, told ABC News that the size and shape of the missile resemble the Tomahawk.

“I do believe this points towards U.S. responsibility for the strike in the area,” he said.

N.R. Jenzen-Jones, director of Armament Research Services, also said the munition seen in the video appeared to be a Tomahawk.

“That indicates it is a U.S. strike,” he said.

Jenzen-Jones earlier cautioned that attributing responsibility for the strike on the nearby school would be difficult without access to munition fragments. He said the new video was still not proof as to who was responsible for striking the school.

“We can only be definitive about the one in the video. Of course, it makes it more likely the surrounding targets were hit by the U.S., but it doesn’t give certainty,” he said.

ABC News has reached out to the Pentagon for a comment.
