A missile strike that hit the Shajarah Tayyebeh primary school in southern Iran, killing more than 170 people, has sparked international outrage as the Iran war continues.

UNESCO called it a “grave violation of humanitarian law”, with authorities and news outlets widely labelling it the deadliest attack of the conflict so far.

The US and Iran were quick to point the finger at each other, with an investigation into what exactly happened and who is responsible underway.

EU News’ fact-checking team, The Cube, looked at satellite imagery and news reports to dissect how the events leading up to and following the tragedy have unfolded.

The timeline

The school was struck in the morning of 28 February, with reports from Iranian state media stating that more than 100 children were among those killed.

During a 3 March briefing, US Central Command said that its attack on Iran — dubbed Operation Epic Fury — prioritised the destruction of IRGC command and control centres along the Hormozgan coastline in the country’s south, to prevent them from closing the Strait of Hormuz.

Videos show that the strikes used Tomahawk missiles, and the US is the only country involved in the conflict that uses them — they are not generic missiles, as US President Donald Trump claimed.

Contrary to the president’s claims, the only countries aside from the US that use or have purchased Tomahawk missiles are Australia, Japan, the Netherlands and the UK, none of which are participating in the war in Iran.

Who blames whom?

US Secretary of Defence Pete Hegseth, meanwhile, said that the US is doing everything in its power to make sure civilians aren’t targeted, and that it will thoroughly investigate any reports to the contrary.

Iran has blamed the US and Israel, with Foreign Minister Seyed Abbas Araghchi stating that such “crimes against the Iranian People will not go unanswered”.

Israel, meanwhile, which has been the US’s key partner in the war in Iran, has denied any involvement in the strike on the school.

“We have checked multiple times and have found no connection between the IDF [Israel Defense Forces] and whatever happened in that school,” Israeli military spokesman Lieutenant Colonel Nadav Shoshani said.

US at fault, says prelim report

However, the New York Times published an article on 11 March stating that a preliminary investigation found that the US was indeed at fault for the strike on the school.

The investigation is still ongoing, with the New York Times reporting that questions remain over why old information was used and who failed to verify it.

Local news outletsstate that the school was indeed used as a military facility in the past before being converted.

The Cube identified satellite images from 2013 showing it was part of the same compound as the base, but more recent photos reveal that it has since been fenced off.

Questioned about the ongoing investigation, Trump has said that he doesn’t know anything about it, but the president is facing increasing pressure at home over the way he has handled the attack on Iran.

Democrats have decried the “horrifying” attack on the Shajarah Tayyebeh primary school and called for a swift probe into the matter, while European leaders call for maximum restraint and assurances that civilians will not be harmed as the war continues.
