A new video geolocated by NBC News appears to show the moment a missile hit a former Islamic Revolutionary Guard Corps compound where a school in Minab was struck and scores of children were reported killed.

The video published by Iran’s semi-official Mehr News was first geolocated by online research group Bellingcat, which said that the missile appeared to be a U.S. Tomahawk.

N.R. Jenzen-Jones, director of the arms intelligence firm Armament Research Services, agreed, telling NBC News the video “appears to show a Tomahawk missile.” He added: “Given the belligerents, this would indicate a U.S. strike.”

The U.S. is the only participant in the war known to have Tomahawk missiles, Bellingcat noted in its reporting.

President Donald Trump claimed over the weekend that Iran was likely responsible for the school strike, while Defense Secretary Pete Hegseth said last week that the U.S. was still “investigating” the incident.

The Trump administration’s preliminary findings show it is increasingly likely that a U.S. munition was used in the strikes, a U.S. official and a person familiar with the investigation told NBC News. The U.S. is still looking into whether the strikes were the result of bad intelligence or poor targeting, the sources said.
