The Iranian military has released a report on its investigation into the helicopter crash that killed the country's president and others. It says investigators did not notice anything suspicious in conversations between the flight crew and air traffic controllers.
The helicopter went down in the northwestern Iranian province of East Azerbaijan on Sunday. All eight people on board, including President Ebrahim Raisi and Foreign Minister Hossein Amir Abdollahian, were killed.
A senior government official blamed inclement weather for the crash. But another senior official claimed that there were no abnormal weather conditions.
The General Staff of the Armed Forces sent investigators to the crash site on Monday and published preliminary findings through the country's state-run media on Thursday.
It said the helicopter was traveling on a planned route when it crashed into a mountain and burst into flames. It added that no bullet traces were found in the wreckage.
The report said the pilot communicated with the other two helicopters in the group about 90 seconds before the accident. It also said nothing unusual was heard in the conversations between the flight crew and air traffic controllers.
The military says it will continue to investigate the matter. It also called on the public to disregard speculations regarding the cause of the accident.
