Of them, 124 are currently hospitalised, including one in critical condition and 13 in serious condition, it added.Iran on Saturday said the US and Israel had targeted its Natanz enrichment complex, though it reported no radioactive leakage.An unnamed Israeli official, quoted by The Associated Press news agency, denied that Israel was responsible for the Natanz strike, but the Israeli army has not released a full statement on the matter.Also on Saturday, the Israeli military announced it had struck a research and development facility at Tehran’s Malek Ashtar University, which it said had been used to develop components for nuclear weapons and ballistic missiles.The military said it “will not allow the Iranian regime to acquire nuclear weapons”.Israel is believed to have developed nuclear weapons by the late 1960s. Its policy of deliberate ambiguity, neither confirming nor denying their existence, was part of a deal quietly struck with Washington, which judged that an open declaration would risk triggering a regional arms race.Abas Aslani, a senior fellow at the Centre for Middle East Strategic Studies in Tehran, told Al Jazeera that Iran has been pursuing an eye-for-an-eye approach designed to re-establish deterrence.“Tehran wants to reduce the gap between words and actions,” he said, adding that Iran’s goal was to make its threats credible enough to underpin a new long-term security arrangement, not to simply force a ceasefire, but to establish deterrence.
