The General Staff of the Iranian Armed Forces on Wednesday released its second report on the May 19 crash, which also killed foreign minister Hossein Amirabdollahian and others.

Based on sampling and tests conducted on the wreckage and parts of the helicopter, as well as the distribution pattern of the debris from the main body, the occurrence of an explosion caused by sabotage during the flight and moments before the impact with the mountainside is ruled out, the report said.
