Reuters and Israeli media have reported that Iran’s Supreme Leader Ayatollah Ali Khamenei has been killed, citing unnamed “senior” Israeli officials. There has been no confirmation from Iranian authorities.

Reporting from Tehran, Al Jazeera correspondent Tohid Asadi said no official statement has been issued in Tehran so far.

He added that Iran’s foreign minister Abbas Araghchi told NBC News that, “as far as I know”, the Supreme Leader and other senior Iranian officials remained in good health.

Asadi also pointed to a statement attributed to Khamenei’s public relations office describing the reports as “mental warfare”.

“Of course, this is going to be huge news if it’s true,” Asadi said.
