Iran launched a cluster warhead missile attack on Tel Aviv in retaliation for the killing of its security chief, Ali Larijani, according to Iranian state television on Wednesday. The strike on the densely populated Israeli city killed at least two people, raising Israel’s death toll in the ongoing conflict to at least 14. Israel has accused Iran of repeatedly using cluster munitions, which disperse multiple explosives over wide areas and are difficult to intercept.

The International Atomic Energy Agency (IAEA) reported that a missile also struck near Iran’s Bushehr nuclear power plant on Tuesday evening, though no damage or casualties were recorded. IAEA chief Rafael Grossi urged all parties involved in the conflict to exercise maximum restraint to avoid nuclear risks.

Israel and the United States have said their attacks on Iran, launched more than two weeks ago, aimed to halt Tehran’s nuclear weapons program. Iran confirmed that Larijani was killed in a recent Israeli strike, following the death of Supreme Leader Ayatollah Ali Khamenei. Iran’s National Security Council added that Larijani’s son and deputy, Alireza Bayat, were also killed in the same attack.
