Israel said the missiles dispersed multiple submunitions mid-air, complicating interception efforts. The overnight attack killed two people in Tel Aviv, bringing the total death toll in Israel since the start of the war to at least 14, according to Israeli authorities.

Iran described the strike as a direct response to the assassination of Larijani, one of the most senior figures killed since the conflict began more than two weeks ago. Tehran confirmed his death on Tuesday, following earlier Israeli statements that he had been targeted in an airstrike.

Iran’s Supreme National Security Council, which Larijani had previously headed as secretary, said his son and deputy, Alireza Bayat, were also killed in a separate Israeli attack on Monday night.

In a separate development, Iran said a projectile struck near the Bushehr Nuclear Power Plant on Tuesday evening but caused no damage or injuries. The country informed the International Atomic Energy Agency of the incident.

IAEA Director General Rafael Grossi renewed calls for maximum restraint, warning of the risk of a nuclear accident if strikes continue near sensitive facilities.

The United States and Israel have said their campaign aims in part to prevent Iran from developing a nuclear weapons programme. The strikes have killed multiple senior Iranian officials, including Supreme Leader Ali Khamenei in the opening phase of the conflict.

Iran’s newly appointed supreme leader Mojtaba Khamenei has rejected proposals to de-escalate, according to a senior Iranian official. Speaking at his first foreign policy meeting since taking office, he said it was not the right time for peace and that Iran would continue its confrontation until its adversaries accepted defeat and paid compensation.

The exchange of strikes underscores the intensifying trajectory of the conflict, with both sides expanding targets and rhetoric while international agencies warn of broader regional and nuclear risks.

The meeting, opened by French President Emmanuel Macron, brings together major nuclear stakeholders including the United States and China, while Russia one of the world’s largest nuclear powers is absent following its invasion of Ukraine.

The summit takes place as global energy markets remain volatile and policymakers reconsider nuclear power’s role in reducing dependence on fossil fuels and meeting climate goals.

Civilian nuclear power faced a sharp decline in public support after the Fukushima nuclear disaster, which intensified safety concerns previously raised by the Chernobyl disaster.However, interest has revived in recent years as governments emphasise energy sovereignty and the need for stable low-carbon electricity sources.

According to the World Nuclear Association, nuclear power currently accounts for roughly nine percent of global electricity production, with about 440 reactors operating across roughly 30 countries.

The conference is co-sponsored by the International Atomic Energy Agency and the International Energy Agency, both of which have called for greater investment in nuclear generation.

IAEA Director General Rafael Grossi said on Monday that around 40 countries had either begun building reactors or were considering doing so.

The agency has projected that global nuclear power generation could double by 2050 if governments accelerate deployment and investment.

China continues to lead new nuclear construction. The IAEA said the country is building 29 reactors in addition to the 57 already in operation.

IEA Executive Director Fatih Birol said Europe in particular has an interest in strengthening energy sovereignty by expanding domestic clean energy capacity.

Birol said this strategy would include scaling up renewable sources such as solar and wind while also enabling what he described as a “strong comeback” for nuclear power in the global energy mix.
