Iran's Interior Minister Ahmad Vahidi affirmed that all forces are being mobilised to locate the crash-site of Iranian President Ebrahim Raisi's helicopter.In a statement broadcast by the Islamic Republic News Agency (IRNA), the Interior Minister indicated that the location of the helicopter has not yet been reached due to the area having steep slopes and forests, as well as heavy rainfall, which has made visibility very limited.In turn, Iran's assistant president for executive affairs Mohsen Mansouri revealed that two contacts were made in several stages with two of the Iranian President's companions in the helicopter that was carrying them.Mansouri indicated that Iran's Ministry of Communications has been able to determine the crash site of the helicopter that was carrying the President.A helicopter carrying the Iranian president Ebrahim Raisi along with foreign minister Hossein Amirabdollahian and other officials suffered a hard landing in the northwestern province of East Azerbaijan earlier Sunday.
