In a preliminary report by Iran's military says it has so far found no evidence of an attack during investigations into the helicopter crash that killed President Ebrahim Raisi, reports "Reuters".
Recall that Raisi, a hardliner who was seen as a potential successor to Supreme Leader Ayatollah Ali Khamenei, died when his helicopter crashed in bad weather in the mountains near the border with Azerbaijan on Sunday.
"No traces of firearms or the like were found in the wreckage of the helicopter, which crashed in a high-altitude area and burst into flames, said the report issued by the General Staff of the Armed Forces. "Nothing suspicious was noticed in the control tower's conversations with the flight crew," he added.
More details will be released as the investigation progresses, the report said.
Raisi was buried in the holy Shia Muslim city of Mashhad on Thursday, four days after the crash that also killed Foreign Minister Hossein Amirabdolakhian and six others.
Experts say Iran has a poor air safety record, with repeated crashes, many involving US-made planes bought before the 1979 Islamic Revolution.
Tehran claims that US sanctions have long prevented it from buying new planes or spare parts from the West to upgrade its own.
We remind you that Russia and Belarus have already blamed US sanctions as the reason.
The US said it had received a request for help, but logistical reasons prevented it.
