Former Iranian President Ebrahim Raisi was killed in a helicopter crash back in May.
The body investigating the case has now revealed that the crash was caused by bad weather.
The final report from the Supreme Board of the General Staff of the Armed Forces stated that the main cause of the crash was the “complex climatic and atmospheric conditions of the region in the spring.”
The report added that the “sudden emergence of a thick mass of dense and rising fog” led to the helicopter’s collision with the mountain.

According to the report, there were no signs of sabotage in the helicopter’s parts and systems.
A preliminary report by Iran’s military had stated in May that no evidence of foul play or an attack had been found during the investigation.
The helicopter carrying 63-year-old Raisi and his team crashed into a foggy mountainside in northern Iran, killing him and seven others, including Foreign Minister Hossein Amir-Abdollahian.
