Manama, Bahrain / Washington D.C. — May 29, 2026: The U.S. Central Command (CENTCOM) issued one of its sharpest operational warnings of the entire US-Iran conflict on Friday, putting all vessels in the vicinity of the Strait of Hormuz on direct notice: any ship observed laying or supporting the laying of naval mines will be immediately targeted by U.S. forces in self-defense. The warning, published through the Joint Maritime Information Center, came amid a fragile ceasefire — and just days after CENTCOM carried out live strikes against Iranian mine-laying vessels in exactly the same waters.

CENTCOM's Exact Warning

U.S. Central Command issued a formal advisory through the Joint Maritime Information Center on Friday, stating: "Iran continues to attempt to impede mine clearance and safe transit of the Strait of Hormuz. Any vessel observed to be engaged in, or supporting, mine-laying activities will be targeted by U.S. forces in self-defense."

The language is deliberately unambiguous. Unlike previous diplomatic statements that left room for interpretation, CENTCOM's Friday advisory functions as a live rules of engagement declaration — signaling to Iranian naval commanders, IRGC boat crews, and third-party vessels that any mine-laying activity near the Strait will be met with lethal force, without further warning.

The May 25 Strikes: What CENTCOM Already Did

Friday's warning was not theoretical. It followed direct action just days earlier. U.S. forces attacked missile sites in southern Iran and boats trying to lay mines near the Strait of Hormuz on May 25, 2026 — with CENTCOM describing the action as self-defense to protect American troops and military assets amid the fragile ceasefire.

CENTCOM spokesperson Capt. Tim Hawkins stated: "U.S. forces conducted self-defense strikes in southern Iran today to protect our troops from threats posed by Iranian forces. Targets included missile launch sites and Iranian boats preparing to lay mines." The targets were two Islamic Revolutionary Guard Corps (IRGC) boats in the Strait of Hormuz which were laying mines, and a surface-to-air missile (SAM) site in Bandar Abbas that was targeting U.S. aircraft.

Iran's IRGC Response: Shot Down a Reaper, Fired at F-35

Following the May 25 strikes, the Iranian Fars news agency relayed a statement from the IRGC, claiming that an MQ-9 Reaper drone was shot down and that air defenses fired at a second MQ-9 and an F-35 Lightning II. The IRGC declared: "The IRGC warns against any violation of the ceasefire by the invading American army and considers its right to reciprocal response both legitimate and certain."

Iranian media also reported explosions near Bandar Abbas and said several members of Iran's Revolutionary Guards were killed in the attacks, with Tehran condemning the strikes as a violation of the ceasefire truce. The U.S., however, maintained that the strikes do not constitute a ceasefire violation — because Iran initiated hostile mine-laying activity first.

The Strategic Stakes: 20% of Global Oil Supply

The Strait of Hormuz carries approximately 20% of the world's oil supply — making Iran's mine-laying campaign one of the most economically consequential acts of naval warfare in decades. A former CENTCOM official described Iran's tactics as a "nightmare more than 30 years in the making" — calling it a "World War I-style" of combat that holds the world's energy supply hostage.

The geography of the Strait of Hormuz continues to favor rapid escalation. The action highlights how anti-ship missiles, naval mines, drones, and fast attack craft can generate strategic effects far beyond their tactical scale — making the Gulf one of the world's most volatile deterrence environments.

The Ceasefire Paradox: Talking Peace While Fighting at Sea

The May 25 strikes came as top Iranian negotiators arrived in Doha for the latest round of talks aimed at ending the months-long conflict — creating a stark contradiction between the diplomatic track and ongoing military action at sea. Both sides simultaneously claim the other is violating the ceasefire, while back-channel negotiations on the 60-day MOU extension remain active.

CENTCOM also confirmed that over the six weeks prior, U.S. forces redirected 100 commercial vessels while enforcing the maritime blockade against Iran — with more than 200 aircraft and warships involved, including the Abraham Lincoln and George H.W. Bush Carrier Strike Groups. Friday's formal mine-laying warning underscores that the U.S. military posture in the Gulf remains fully combat-ready — regardless of whatever diplomatic progress is being made in Doha or Washington.
