JERUSALEM (AP) — Satellite images, expert analysis and information released by the U.S. and Israeli militaries suggest an explosion that killed scores of Iranian students at a school was likely caused by U.S. airstrikes that also hit an adjacent compound associated with the regime's Revolutionary Guard.
The Feb. 28 strike, which had the highest reported civilian death toll since the war began, has come under staunch criticism from the United Nations
and human rights monitors. More than 165 people were killed, most of them of children, in the blast during school hours at Shajareh Tayyebeh Elementary School, according to Iranian state media.
Satellite images taken Wednesday and reviewed by the The Associated Press show most of the school in the city of Minab, some 1,100 kilometers (680 miles) southeast of Tehran, reduced to rubble, a crescent shape punched into its roof. Experts say the tight pattern of the damage visible on the satellite photos is consistent with a targeted airstrike.
Iran has blamed Israel and the United States for the blast. Neither country has accepted responsibility. Asked about the strike at the school at a Pentagon press briefing Wednesday, Defense Secretary Pete Hegseth said, “All I can say is that we’re investigating that. We, of course, never target civilian targets. But we’re taking a look and investigating that.”
Several factors point to a U.S. strike. One is the launching of an assessment of the incident by the U.S. military. According to the Pentagon's instructions on processes for mitigating civilian harm, an assessment is launched after a group of investigators make an initial determination that the U.S. military may bear culpability.
Another is the location of the school — next to a base of the Revolutionary Guard in Hormozgan Province and close to a barracks for its naval brigade. The U.S. military has focused on naval targets and acknowledged strikes in the province, including one in the vicinity of the school.
Israel, which has denied conducting the strike, has focused on areas of Iran closer to Israel and hasn’t reported conducting any strikes south of Isfahan, 800 kilometers (500 miles) away. The U.S. is operating warships in the Arabian Sea, including the USS Abraham Lincoln aircraft carrier, within range of the school.
When asked by the AP about its findings, the U.S. military’s Central Command said, “It would be inappropriate to comment given the incident is under investigation.”
“My assumption is that probably there were some activities recently there and they detected and tracked them, but ... they weren't aware or didn't have an up-to-date database that a girls' school was there and they bombed it," said Farzin Nadimi, a senior fellow at the Washington Institute for Near East Policy who studies Iran’s military.
The school is adjacent to a walled compound labeled on maps as the Seyyed Al-Shohada Cultural Complex of the Guard, which included a pharmacy, gym and sports field.
In addition to the school, satellite photos show that blasts struck at least five buildings in the Guard compound, leaving the area pocked with craters, charred holes in roofs and piles of rubble. Historical satellite imagery shows the school building was not separated from the Guard compound until about a decade ago when a wall was built between them.
Iranian online map applications show a living quarters for the Assef Brigades about 150 meters (165 yards) from the school, inside the Revolutionary Guard compound. The 16th Assef Coastal Missile Group is part of the Guard's navy, Nadimi said. The 1st Naval District, which the Assef Brigades belong to, is responsible for the Strait of Hormuz, the narrow mouth of the Persian Gulf through which a fifth of all oil and natural gas traded passes. The strait has been a particular point of conflict in the war.
In the aftermath of the strike, video from Iran's state broadcaster verified by the AP using satellite imagery showed dozens of fresh graves dug at a nearby cemetery. Nadimi said it is likely the school taught daughters of Guard personnel.
The strike has drawn wide condemnation from the secretary-general of the United Nations and international human rights groups. The criticism comes amid reports that airstrikes have also hit other schools in Iran.
The London-based conflict monitoring organization Airwars is reviewing three other school strikes that caused casualties. In addition to those, in the last 48 hours the U.S.-based Human Rights Activists News Agency reported at least two more schools were struck.
Targeting schools would be a clear violation of international laws governing armed conflict, said Elise Baker, a senior staff lawyer at the Atlantic Council, a Washington-based nonprofit think tank.
“Strikes can only legally target military objectives and combatants, but the school was a civilian object and the students and teachers were civilians,” Baker said. “The school’s proximity to (Guard) facilities and the attendance of children of (Guard) members at the school does not change that conclusion: It was a civilian object.”
Three experts told the AP the satellite imagery and videos from the scene strongly suggested multiple munitions hit the compound. Complicating any assessment is the lack of images of bomb fragments from the blast. No independent agency has reached the site during the war to investigate, either.
There are no craters or evidence of bombs hitting in the surrounding neighborhood, suggesting a great degree of accuracy, said Corey Scher, a researcher who uses satellite imagery and radar data to study landscape changes in armed conflict zones.
“All the strikes are clustered within the walled-off compound," Scher said. "That’s one level of precision at the block level. And then most of the strikes are basically leading to direct hits on buildings. That’s another level of precision.”
Scher said the school and the other buildings struck in the compound showed damage consistent with the use of air-to-surface munitions.
“They didn’t explode in the air above the building," he said. “It looks like the explosion happened at the time they hit the surface, whether it was the building or the ground."
Sean Moorhouse, a former British Army officer and explosive ordnance disposal expert, said the available satellite imagery was insufficient to determine exactly what type of munitions were used in the strike, but he said the visible damage was consistent with what would be expected with impacts from multiple 2,000-pound (900-kilogram) high-explosive warheads. He said the multiple precise impacts would undercut any suggestion that a malfunctioning Iranian missile hit the school.
N.R. Jenzen-Jones, the director of Armament Research Services, said the school and Guard compound were targeted with “multiple simultaneous or near-simultaneous strikes." He said in videos of the school taken immediately after the strike, smoke can be seen rising from the Guard compound. There were also impacts on multiple buildings visible in satellite images and media reports citing witnesses who said they heard multiple explosions.
“If indeed it is confirmed that an American or Israeli strike hit the school, there are several potential points of failure in the targeting cycle," Jenzen-Jones said. “We might be seeing an intelligence failure, likely rather early in the process, which misidentified the target or failed to update a targeting list following the building’s change in use.”
