The Persian Gulf Strait Authority (PGSA) said on Thursday that any transit outside approved routes would be considered unauthorized, with responsibility for any consequences placed on the vessel owner, operator and captain.
The warning came as the United Kingdom Maritime Trade Operations (UKMTO) agency reported that a cargo vessel was struck approximately 7.5 nautical miles southeast of one of Oman's ports.
The master reported no casualties and no environmental impact from the attack, though the vessel sustained physical damage to its hull from the unknown projectile.
