The reports that Iran hit Didmar Island in the As-Salma Archipelago with ballistic missiles are false.
Current NASA fire images show no fire anywhere in the Strait of Hormuz, contradicting a post by an Iranian state-sponsored outlet claiming a large fire from a missile strike on an island. In addition, the Iranian military has not announced any such operation, nor have there been other reports from other sources verifying these claims.
The second image was taken directly from the Rerum Novarums MiniMap, using the FIRMS feature; Shows no fire or history of fire anywhere in the Strait of Hormuz. If an Iranian ballistic missile, especially one fueled by solid fuel, were to hit a piece of critical US or Omani infrastructure, there would be a fire.
