An Iranian official told the New York Times that Tehran was angered after Oman allowed vessels to use alternative routes through the Strait of Hormuz without coordination with the Islamic Revolutionary Guard Corps. The official said the dispute led to an Iranian drone firing at a ship and a temporary halt to maritime traffic. While Oman has been cooperating with Iran on navigation management and facing U.S. pressure to keep the waterway open, the source warned that Oman cannot guarantee ship security without Iranian participation and that Tehran will not tolerate any third‑party interference in the strait.
