US aerial attack on Iranian school

Available evidence shows that the Minab school was attacked by the US, as part of an attack on the Iranian military buildings right nearby. I think this convincing proof that US fired at a missile at that school, not intentionally, but through assuming erroneously that it was a military structure. The US military had pictures that should have indicated the building was a school, so it had the responsibility to recognize this and spare the school. I think that makes the attack a culpable error, but that is not as bad as an intentional atrocity.
