Demonstrations have broken out Sunday across Iran following the announcement that Supreme Leader Ayatollah Ali Khamenei was killed in US and Israeli military strikes.

The developments have dramatically escalated tensions in the Middle East and triggered widespread public reaction within Iran.

Iran’s state television early confirmed that Khamenei lost his life during the US‑Israel attacks, declaring that Iran’s “Islamic revolution leader has reached martyrdom.”

The government also insтιтuted a 40‑day national period of mourning and a seven-day official holiday.

Large crowds took to the streets in cities across Iran in response to the news of Khamenei’s death.

Iranian media said demonstrators bearing Iranian flags gathered at urban centers to voice their grief.

In Tehran, hundreds ᴀssembled in Inkilap Square, raising flags and posters of Khamenei, and shouting slogans condemning the US and Israel.

In the holy city of Qom, hundreds gathered at the shrine of Hazrat Masume to denounce the attacks.

In Mashhad, mourners observed a symbolic gesture of grief by draping a black flag over the dome of the Imam Reza Shrine, one of Iran’s most revered religious sites, and many were seen shedding tears in the surrounding area of the shrine.
