Iran’s state-run media said the strike occurred on Saturday in Minab, located in Hormozgan province, leaving dozens dead and many others injured.

Rescue teams were said to be combing through the rubble late into the day, as authorities confirmed that 63 others sustained injuries in the attack.

Local reports indicated that emergency responders were still clearing debris at the school site hours after the incident.

Images shared by Iranian officials showed damaged structures and rescue workers at the scene.

Iran’s Foreign Minister, Abbas Araghchi, reacted on social media platform X, describing the strike as an attack on “innocent children.”

“These crimes against the Iranian People will not go unanswered,” Araghchi wrote.

The incident forms part of a broader escalation involving Israeli and United States military actions across Iran in recent weeks.

The renewed hostilities have heightened tensions in the Middle East, with fears of a wider regional conflict.

Israeli authorities have not immediately issued a detailed statement regarding the specific strike in Minab.

Russia has strongly criticised the latest military actions against Iran.

In a statement issued on Saturday, Moscow described the airstrikes by the United States and Israel as a “deliberate, premeditated, and unprovoked act of armed aggression” against a sovereign state.

“The scope and character of the military, political, and propaganda preparations that preceded this reckless step leave no doubt that this is a deliberate, premeditated, and unprovoked act of armed aggression against a sovereign and independent UN member state,” the Russian government said.

Russia accused Washington and Tel Aviv of violating international law and fundamental global norms.

The Kremlin also expressed concern over the timing of the strikes, noting that they occurred amid renewed diplomatic engagements over Iran’s nuclear programme.

Russia further described as “unacceptable” reports of attacks on nuclear facilities operating under safeguards of the International Atomic Energy Agency.

It warned that escalating tensions could destabilise the global nuclear non-proliferation regime and push the region toward what it called “a humanitarian, economic, and potentially even radiological disaster.”

“We call for an immediate return to a political and diplomatic track,” the statement added, stressing Moscow’s readiness to support peaceful solutions grounded in international law.
