The claim is false. No credible reports confirm Iran or the IRGC confessed to mistakenly bombing the Minab school on Feb 28. All sources (NYT, BBC, Guardian, Al Jazeera, Wikipedia, etc.) state a missile hit the girls' elementary school during US-Israeli strikes, near an IRGC naval base, killing 148-165 (mostly children). Iran blames the attacks; US/Israel investigating. The Telegram screenshots lack official backing and appear fabricated for narrative. Fog of war, but no self-strike admission.
