Oman's Maritime Security Center and Ministry of Defence issued an alert on Saturday 30 May warning of an object "suspected to be a floating mine" inside Omani territorial waters in the Strait of Hormuz, advising vessels to keep a SAFE distance 1. The centre is the Omani government body that coordinates maritime safety in and around the country's waters.
Oman gave no attribution for the object and reported recovery as unconfirmed at the time of the alert. This account does not assert who placed it. Omani waters sit outside Iran's declared blockade zone, which makes the location itself the established fact rather than the source.
Earlier mine and projectile incidents sat in or near that Iranian zone, including the tanker Olympic Life struck off Muscat on Tuesday 26 May . A suspected mine drifting into the waters of the state mediating between Washington and Tehran is a different fact, and it compounds the pressure on Oman as broker. It lands the same weekend Washington threatened that same mediator with sanctions over Hormuz tolls , squeezing Muscat from the kinetic and diplomatic tracks at once.
