The aerial footage showed that the streets were packed with people.
Iranian Interior Minister Ahmad Vahidi was among the ranking participants in the funeral procession.
He said the demise of the president and his entourage, including Foreign Minister Hossein Amirabdollahian, beamed the Iranians’ unity to the world.
The initial report on the fatal crash, released by the General Staff of Iran’s Armed Forces, confirms that the accident happened after the helicopter hit the mountain and caught fire and rules out the possibility of any plot.
