Iranian state media has confirmed the death of Supreme Leader Ali Khamenei. The 86-year-old ayatollah, who had ruled Iran for over 36 years, is described as having been “martyred” in government statements announcing a period of 40 days of public mourning.

Under Iran’s constitution, an interim council will assume authority while the Assembly of Experts — a body of 88 Islamic clerics — selects a new supreme leader. Israel has reported that its initial strikes targeted and killed seven senior defense and intelligence officials, as well as at least 30 top military and civilian leaders within the regime.

President Trump stated on social media that Khamenei was “one of the most evil people in History” and that his death resulted from U.S. and Israeli operations. He further claimed many Iranian security forces no longer wish to fight and are seeking immunity, urging them to merge with “Iranian Patriots” for national restoration.

Iran has designated its president, head of judiciary, and a jurist from the Guardian Council to oversee the transition period following Khamenei’s death. The Assembly of Experts is set to appoint his successor as soon as possible, though ongoing security concerns may hinder the process.

Khamenei was appointed to the position on the same day that Ruhollah Khomeini died.
