Iranian officials have spoken to two people on the same helicopter as President Ebrahim Raisi since it crashed Sunday, Iranian Vice President for Executive Affairs Mohsen Mansouri told the country's semi-official FARS news agency. 

Three helicopters were flying on the same route before two lost contact with Raisi's helicopter, Mansouri said.

"The Ministry of Communications and other security agencies have identified the incident area within a 2-kilometer radius. Due to weather conditions, access to the area is challenging," he said.
