A new video that has surfaced shows that a US-made missile was responsible for the strike on a girls' school where hundreds of people were killed.
Iranian authorities had reported that at least 165 to 180 people, a majority of them aged between 7 and 12, were killed in the attack 95 others were injured.
The seven-second video was posted by Iranian Mehr News and then shared online by Trevor Ball, a former U.S. Army Explosive Ordnance Disposal technician. Ball said on X that the video showed a US-made Tomahawk missile.
Jeffrey Lewis, a professor of global security at Middlebury College, also said that the missile appeared consistent with a Tomahawk cruise missile. The US is the only country known to operate the missile.
Satellite imagery reviewed by AP showed that the school located in Minab city, some 1,100 kilometres southeast of Tehran, was completely demolished after the strike. The pattern of damage was crescent-shaped, making it consistent with a targeted airstrike.
On Saturday, President Trump accused Iran of being responsible for the attacks.
"Based on what I've seen, I think it was done by Iran," Trump said. "Because they're very inaccurate, as you know, with their munitions. They have no accuracy whatsoever. It was done by Iran." Pete Hegseth also spoke beside Trump, saying that the US was investigating. "But the only side that targets civilians is Iran," he added.
The video footage was geolocated by an online research group Bellingcat, NPR reported. The video appeared to be authentic and contained details of the location of the strike which could not be produced by AI.
Satellite imagery of the location, obtained by NPR, showed that a health clinic and other buildings near the school were also attacked.
Local officials have claimed that the airfield and base close to the school were abandoned for over a decade. The school was also separated by a compound built around 2013 and 2016. The airstrip, meanwhile, was removed in 2024 according to satellite imagery.
Some online posts showed that the locatonn was being turned into housing development.
A Fars report also showed that the clinic, which was also targetted, was opened by by IRGC chief Hossein Salami in 2025, who was killed in an Israeli strike later that year.
Jeffrey Lewis said that the school and the clinic were possibly struck based on outdated targeting information.
Israel, meanwhile, had also denied any involvement "We are not aware at the moment of any IDF operation in that area," Israel Defence Forces spokesperson Nadav Shoshani told NPR on Monday.
