A member of the European Parliament (EP) called for an immediate and impartial investigation into the deadly attack on a girls’ elementary school in Iran’s Minab, saying the strike may have been deliberate and could constitute a war crime, according to Al Jazeera, citing Iranian media.

Speaking at a memorial gathering outside the Iranian embassy in Brussels, Slovak MEP Milan Uhrik said the scale and nature of the attack suggested it was preplanned. According to him, this was a war crime, and the European Union and European countries should not be involved in such actions, Al Jazeera reported.

He drew parallels with civilian casualties in Gaza, Lebanon and Beirut, saying attacks on women, children and the elderly reflected a willingness to target non-combatants to create fear and panic for strategic purposes.

Uhrik said he had sent a letter to the European Commission demanding an investigation into the incident. He criticised European institutions and leaders as “weak” for failing to examine the attack and accused them of being unable to resist what he described as the aggressive policies of Israel and the United States, as per Al Jazeera.

Iran said that an attack on February 28 on a girls’ elementary school in Minab killed 175 people, including 168 female students, and injured 95 others.

US President Donald Trump stated in an interview with the press on Friday that the Minab school strike was still “under study.”

Soon after the strike, Trump blamed the Iranian military for the incident but did not provide evidence to support the claim, according to Al Jazeera and the Guardian.
