An Iranian ballistic missile pierced Israel's multilayered air defenses and struck a building in the southern city of Dimona on Saturday evening, wounding 27 people in what Israeli officials described as a direct hit. The city houses the Shimon Peres Negev Nuclear Research Center, though no damage to the facility was reported and radiation levels remained normal.

Magen David Adom emergency services treated the casualties, most suffering from shrapnel wounds. Among them was a 12-year-old boy, with others including a 10-year-old boy in moderate condition. Fires broke out in surrounding buildings, and walls collapsed between structures due to the impact of the hundreds-of-kilograms warhead. The Israeli military confirmed the strike and noted that interceptors missed the missile, announcing a review of the incident.

Iranian state media claimed the attack targeted nuclear facilities in retaliation for a U.S. strike earlier Saturday on the Natanz nuclear enrichment complex in central Iran. Iran's atomic energy organization reported no radioactive leakage from Natanz, and the International Atomic Energy Agency confirmed no rise in off-site radiation levels while urging all parties to exercise restraint to prevent a nuclear accident. The IAEA stated it had no information indicating damage to Israel's Negev nuclear research center.

This exchange marked day 22 of the war between Israel, backed by the United States, and Iran, which began on February 28 with U.S. and Israeli airstrikes that killed Supreme Leader Ali Khamenei and targeted Iranian nuclear and military sites. Iran has responded with hundreds of ballistic missiles and drones against Israel and U.S. bases across the Middle East, including in Gulf states. Hezbollah has also fired rockets into northern Israel, prompting an Israeli ground incursion into southern Lebanon.

The Dimona strike followed another Iranian missile impact in nearby Arad, where 65 to 74 people were wounded in what medics called the largest single-attack injury toll since the war's start. Sirens sounded repeatedly across southern Israel as Iran launched additional missiles.

Iranian military sources described the attacks as a shift to disproportionate retaliation, vowing to 'raise the cost' by striking multiple enemy infrastructures. 'The enemy must have realized by now that if they attack one infrastructure, we will attack several,' one source told Tasnim News Agency.

Israel's defense establishment views the strikes as part of Iran's managed escalation, with experts noting Tehran's retained command over its missile forces despite heavy losses. U.S. President Donald Trump stated American strikes on Iranian nuclear sites, including prior operations at Natanz, have significantly degraded Tehran's capabilities.

The conflict has caused thousands of deaths, primarily in Iran, disrupted global oil flows through the Strait of Hormuz, and drawn international calls for de-escalation amid fears of broader regional involvement.
