Iranian president Ebrahim Raisi's 'life is at risk' after he was involved in a helicopter crash near the border with Azerbaijan.

A frantic search mission is underway after the aircraft, which was traveling in Iran's East Azerbaijanprovince near Jolfa, around 375 miles northwest of Tehran, suffered a 'hard landing' on Sunday, according to Iranian state television.

The helicopter was one of a convoy of three and foreign minister Hossein Amirabdollahian, Friday prayer Imam Seyyed Mohammad-Ali Al-Hashem and other high-ranking officials were also reportedly on the helicopter with the president.

The lives of President Raisi and foreign minister Amirabdollahian are at risk following the crash over mountain terrain, an Iranian official told Reuters.

All army and Iranian guard resources are being utilized in the search efforts for the helicopter. 

Some began urging the public to pray for Raisi and the others on board as rescue crews sped through a misty, rural forest where his helicopter was believed to be.
