Multiple weapons experts have disputed a US claim that Iran may have been responsible for a deadly strike on the town of Lamerd on the first day of the war.
Six experts - who examined footage of the strike and all commented independently - contested the US suggestion that it was an Iranian missile, citing the missile's visual features, the way it exploded, its trajectory and the number of strikes in the area as the basis for their analysis.
Iranian officials have said 21 people, including four children, were killed.
BBC Verify originally reported on the strikes on 28 March, citing experts who said it was likely a US Precision Strike Missile (PrSM) was used. The US Central Command (Centcom) - which oversees US military operations in the Middle East - declined to comment for that report.
Centcom then released a statement on 31 March denying it was a US missile, instead saying that footage of the attack was consistent with an Iranian Hoveyzeh cruise missile.
