Political analysts and observers were outraged on Thursday after an investigation determined that the U.S. was likely responsible for a Feb. 28 strike on a girls' school in Iran that killed 175 civilians, many of whom were children.

The New York Times reported on Thursday that the strike on the girls' school in Minab was "severely damaged" around the same time that U.S. forces were conducting an attack against an "adjacent naval base operated by the Islamic Revolutionary Guards Corps." The Times added that "official statements ... suggest they were most likely to have carried out the strike."

"In the several days since the attack, U.S. officials have neither confirmed nor denied responsibility," according to the report. "Defense Secretary Pete Hegseth said on Wednesday that an investigation was underway. Nadav Shoshani, an Israeli military spokesman, told reporters on Sunday that 'as of now,' he was not aware of any Israeli military operation 'in that area' at the time."

"U.S. officials in public statements have indicated that on the day in question, U.S. planes were conducting operations in the region where the school was located," it added.

Political analysts and observers expressed outrage on social media.

"It is unconscionable that there has still been no attempt by either the US or Israel to account, let alone apologise, for the killing last Saturday of more than 150 people at the Shajareh Tayyebeh girls' school in Minab, southern Iran," Peter Westmacott, former British Ambassador to Turkey, posted on X.
