To critics, the bombing of the school has become emblematic of the horrors of the war that the US and Israel have unleashed, and that Iran has responded to by launching thousands of missiles and drones not just at Israel and US facilities across the region, but also at Gulf neighbours who have tried hard to not get sucked into the conflict.So what do we know about the totemic incident that has shaped, for many, the early days of the war?What happened in the Iran school strike?The girls’ school, Shajareh Tayyebeh, was located in the city of Minab, near a base belonging to the Islamic Revolutionary Guard Corps (IRGC).It was hit by a missile on February 28 at approximately 10:45am local time (07:15 GMT), a peak hour for classroom activity. The blast destroyed the two-storey building, causing the roof to collapse on students and teachers inside.At least 170 people, most of them children, were killed. Dozens of others were injured.The school is located in Minab, in Iran’s strategic Hormozgan province, which overlooks the Strait of Hormuz and hosts several IRGC naval facilities.While Iran immediately attributed the strike to the US-Israel coalition, both nations denied responsibility.Satellite images showed the school intact earlier that morning. US and Israeli air raids had begun across Minab and other parts of Hormozgan that morning.A screengrab shows what experts say appears to be a US Tomahawk missile hitting near the Shajareh Tayyebeh girls’ school in Minab, Hormozgan province, Iran, on February 28, 2026, amid the US-Israeli war with Iran [Handout/Mehr News via Reuters]Who does Iran blame for the attack?Iran blamed both the US and Israel for the strike.On February 28, Iranian Foreign Minister Abbas Araghchi shared a photo of the attack, which he said destroyed the girls’ school and killed “innocent children”.“These crimes against the Iranian People will not go unanswered,” Araghchi wrote in a post on X.Iran’s Ministry of Foreign Affairs spokesperson Esmaeil Baghaei also slammed the “blatant crime” and urged action from the United Nations Security Council.What does the evidence point to?Footage from the scene suggests the school was likely hit by a Tomahawk missile.Preliminary investigations suggest the school may have been hit by a US missile because of a targeting error, though the exact circumstances remain under investigation.Analysts say the strike may have been caused by outdated targeting information, as the school is on the same block as buildings used by the IRGC’s navy and the site of the school was originally part of the base.For years the school had been separated and had its own walls and entrances.“It seems that the United States Central Command did not keep its target list up to date,” Mark Cancian, a retired Marine Corps colonel and senior adviser with the Washington-based Center for Strategic and International Studies think tank, told Al Jazeera.“Apparently, the building shifted some years ago from military use to the school and the Central Command targeting cell did not pick up that change,” he added.The Shahid Absalan clinic, under the supervision of the IRGC navy’s medical command, is about 238 metres (780 feet) from the site, while the Seyed al-Shohada IRGC cultural complex is 286 metres (938 feet) away.The adjacent Martyr Absalan Specialised Clinic (lower centre, in yellow), which opened in early 2025 and was separated by an independent civilian entrance, sustained no damage during the latest bombardment [Google Earth/Al Jazeera]What has the US said about the strike?US President Donald Trump initially suggested that Iran itself may have been responsible for the strike – even though there was no evidence then, nor now, suggesting any Iranian role in the attack.“Based on what I’ve seen, that was done by Iran,” Trump said on Saturday. “We think it was done by Iran because they are very inaccurate, as you know, with their munitions. They have no accuracy whatsoever. It was done by Iran.”Pete Hegseth, the US defence secretary, was standing behind Trump at the time. He declined to endorse Trump’s assessment and instead reiterated that the Pentagon was investigating the incident.However, The New York Times reported on Wednesday that the school was hit by a US Tomahawk missile because of a targeting error. The newspaper, citing US officials, said the investigation was ongoing, but preliminary findings indicated the US was responsible.Asked by reporters about the report, Trump said: “I don’t know about it.”Trump also told reporters on Monday that Iran “also has some Tomahawks” – a claim widely dismissed by military experts.Secretary of State Marco Rubio said last week that the US would not intentionally target a school.“Members of [Trump’s] administration have been saying an investigation is under way and that they can’t comment on an open investigation,” Al Jazeera’s Mike Hanna reported from Washington, DC.What has Israel said?Israel has denied any involvement.“We have checked multiple times and have found no connection between the [Israeli army] and whatever happened in that school,” Israeli military spokesman Lieutenant Colonel Nadav Shoshani said.What are Democrats asking for in the US?Nearly all US Senate Democrats have signed a letter to Hegseth calling for a “swift investigation“The results of this school attack are horrific. The majority of those killed in the strikes were girls between the ages of 7 and 12 years old. Neither the United States nor the Israeli government has ‌yet taken responsibility for this attack,” the letter, signed by 46 senators, said.The letter asked for answers to a series of questions, including whether US forces conducted ⁠the strikes, what steps the military has taken to prevent and ⁠mitigate civilian harm, and what role artificial intelligence tools have played in operations.If the US role is confirmed, “it would be embarrassing for the military since they have otherwise conducted a pretty sound operation. It will feed some of the antiwar sentiment in Congress and in the population”, Cancian said.Has this happened before?For all of the US’s claims of targeting only military facilities and individuals, its armed forces have a long history of killings – followed at times, with cover ups – of civilians.During the 1999 NATO bombing of Yugoslavia, the US struck an annex of the Chinese embassy in Belgrade after misidentifying the building as a Yugoslav military facility.The strike killed three Chinese journalists and injured more than 20 people.Washington later said the bombing occurred because intelligence analysts relied on outdated maps, which mistakenly identified the embassy compound as a military target.The incident triggered a major diplomatic crisis with China, leading to large protests outside US diplomatic missions in Beijing and other cities.Chinese students break through a line of police officers at the US embassy in Kyiv, Ukraine, on May 11, 1999, during a protest against the bombing of the Chinese embassy in Belgrade and against the NATO bombing campaign on Yugoslavia [File: Sergei Supinsky/EPA]“In 1991, during Desert Storm, the US also struck the Amiriyah bunker in Baghdad, believing it was a command-and-control facility,” Cancian explained.
