The claim “The missile that fell on a girls’ school in Iran was a Raduga Kh-55 launched by…” is not supported by the most reliable investigations so far.

What verified investigations say
The strike occurred on 28 February 2026 at the Shajareh Tayyebeh Girls School in Minab, where many schoolchildren were killed.

Independent analyses by journalists and weapons experts found evidence pointing to a U.S. cruise missile, most likely a Tomahawk cruise missile.

Satellite imagery, video footage, and missile fragments reportedly matched components previously documented from Tomahawk missiles.

U.S. officials themselves said an internal investigation suggested the strike was likely carried out by U.S. forces, though the final conclusion had not yet been officially confirmed.

About the Kh-55 claim
The Kh‑55 cruise missile is a Soviet-designed air-launched cruise missile used by several countries, including Russia and Iran.

However:

Claims that the school was hit by a Kh-55 launched by Iran or another actor mainly circulate on social media and forums.

Those claims have not been confirmed by major investigations or credible evidence.

Fact-checking reports indicate several misinformation narratives spread online after the attack.

Bottom line
The Kh-55 explanation is currently unverified and largely part of online speculation.

The strongest available evidence points to a Tomahawk cruise missile, with investigations still ongoing.

Because the incident happened during an active conflict, final responsibility may take time to be fully confirmed.
