The investigative group Bellingcat says newly released video "appears to contradict" U.S. President Donald Trump's claim that Iran was responsible for an explosion at an Iranian school that killed over 165 people at the start of the war raging in the Mideast.

It comes as mounting evidence points to U.S. culpability for the Feb. 28 strike, which hit a school adjacent to a Revolutionary Guard base in Minab, Iran, in the country's southern Hormozgan Province. Experts interviewed by The Associated Press, citing satellite image analysis, say the school was likely struck amid a quick succession of bombs dropped on the compound.
