Iran warns of naval mine deployment in Gulf if US or Israel launch attacks

Iran has issued a warning that it could deploy naval mines across key waterways in the Persian Gulf if its coastal territory or islands come under attack from the United States or Israel, in a move that could heighten risks to one of the world’s most critical energy corridors.

In a statement released on Monday through state media, Iran’s defence council said any military action targeting its shoreline would trigger measures aimed at restricting access across maritime routes in the region. These measures, it indicated, would include the placement of various types of naval mines, including drifting devices that could be deployed from coastal areas.

The warning underscores escalating tensions in the region and highlights the strategic importance of the Gulf, where a significant share of global oil and gas shipments transit daily. Any disruption to these routes could have immediate implications for international energy markets and supply chains.

The defence council, which operates under Iran’s Supreme National Security Council, was established following a brief but intense 12-day conflict with Israel in June 2025. Since then, it has played a central role in shaping Iran’s defensive posture and signalling its response to perceived external threats.

While the statement did not indicate any imminent military action, it reflects growing concerns over the potential for confrontation involving regional and global powers. Analysts say the use of naval mines—historically employed to restrict maritime movement—could significantly impact shipping lanes, insurance costs, and energy prices if tensions escalate further.

The Strait of Hormuz, a narrow passage linking the Gulf to global markets, remains particularly vulnerable in such scenarios. Even limited disruptions in this area have previously led to volatility in oil prices, underlining the broader economic stakes tied to regional security.

Iran’s latest remarks come amid continued geopolitical strain in the Middle East, with diplomatic efforts ongoing but fragile. Observers warn that any escalation involving major powers could quickly spill over into global markets, particularly in the energy sector.
