Pakistan’s National Hydrographic Office issued an urgent navigational warning on June 19, 2026, confirming the presence of a naval mine near the northwest tip of Oman’s Musandam peninsula in the Strait of Hormuz. The advisory, broadcast through the Navarea IX system, urged all vessels to exercise extreme caution in waters that carry approximately 20% of the world’s oil supply.

The mine warning dropped on the same day the US and Iran announced a deal aimed at normalizing shipping routes and dialing down tensions in the very same chokepoint.

A crisis months in the making

The Strait of Hormuz has been a flashpoint since late February 2026, when Iran began strategically deploying sea mines to restrict maritime passage. By early March, the situation had escalated enough to prompt a significant US naval response, with more than two dozen vessels deployed to the area.

Oman issued its own mine warning on May 30, 2026, and Iran has also flagged hazards in the area. Pakistan’s warning is the latest in a pattern that suggests the Strait remains littered with threats, even as diplomats work to cool things down. Mediation efforts have actually taken place in Pakistan itself, which gives the country’s hydrographic office a front-row seat to the crisis.
