Explosions have rung out across Tehran as the war entered its fourth day with the United States and Israel continuing to pound Iran’s capital and numerous other cities and locations after the assassination of Supreme Leader Ali Khamenei.

Iran continued on Tuesday to retaliate against Israel and throughout the Gulf where nations host US assets.

At least 787 people have been killed in US-Israeli strikes on a minimum of 131 cities across Iran, the Iranian Red Crescent Society said on Tuesday.

Israel’s military said it had “struck and dismantled” the headquarters of Iran’s state radio and television broadcaster, the Islamic Republic of Iran Broadcasting (IRIB), accusing it of “calling for the destruction of the State of Israel and for the use of nuclear weapons”.

In a post on Telegram, IRIB reported explosions near its headquarters in Tehran but said there had been no disruption to its operations.

Tehran’s streets have been largely deserted as people take shelter during the air strikes.

Iranian media also reported explosions in the city of Karaj, just outside Tehran, as well as in the central city of Isfahan.

Iran held a mass funeral on Tuesday for 165 schoolgirls and staff killed on Saturday in what Iran said was a US-Israeli attack on a school in the southern city of Minab.
