According to the Iranian Student News Agency (ISNA): "unofficial sources are reporting the martyrdom of some of the Iranian president's companions in the crash area."
The Iranian media confirmed that it is highly likely that President Raisi died in an accident and that the search from the air was aborted due to heavy fog.
Earlier, a video was published of Raisi, the Iranian foreign minister and two senior officials from Azerbaijan who flew together in the president's personal helicopter before communication was cut off.
The Iranian government will convene for an emergency meeting in the office of the country's Supreme Leader, Seyyed Ali Khamenei.
The Revolutionary Guards channel has raised a black flag for its television broadcasts as a signing of mourning for the fallen leader.
