Israel’s Air Force launched a massive strike on Tehran early Friday, destroying the underground emergency bunker of Iran’s former supreme leader, Ayatollah Ali Khamenei.

According to the IDF, around 50 Israeli fighter jets dropped roughly 100 bombs on the heavily fortified site, which was buried beneath Iran’s sprawling “leadership complex” in the Iranian capital.

Despite Khamenei’s death in a strike at the beginning of the conflict, Israeli officials said the complex continued to serve as an operational hub for senior members of the Iranian government and military leadership.
