Shippers warned to steer clear of Iranian waters

DUBAI, United Arab Emirates — Western-backed maritime forces in the Middle East warned shippers traveling through the strategic Strait of Hormuz to stay as far away from Iranian territorial waters as possible to avoid being seized, a stark advisory amid heightened tensions between Iran and the U.S.

A similar warning went out to shippers earlier this year ahead of Iran seizing two tankers traveling near the strait, the narrow mouth of the Persian Gulf through which 20% of the world’s oil passes.

While Iran and the U.S. now near an apparent deal that would see billions of Iranian assets held in South Korea unfrozen in exchange for the release of five Iranian-Americans detained in Tehran, the warning issued this weekend shows that the tensions remain high at sea.

Already, the U.S. is exploring plans to put armed troops on commercial ships in the strait to deter Iran amid a buildup of troops, ships and aircraft in the region.

U.S. Navy Cmdr. Timothy Hawkins, a spokesman for the Mideast-based 5th Fleet, acknowledged the warning had been given, but declined to discuss specifics about it.

A U.S.-backed maritime group called the International Maritime Security Construct “is notifying regional mariners of appropriate precautions to minimize the risk of seizure based on current regional tensions, which we seek to de-escalate,” Hawkins said. “Vessels are being advised to transit as far away from Iranian territorial waters as possible.”

Separately, a European Union-led maritime organization watching shipping in the strait has “warned of a possibility of an attack on a merchant vessel of unknown flag in the Strait of Hormuz in the next 12 to 72 hours,” said private intelligence firm Ambrey.

“Previously, after a similar warning was issued, a merchant vessel was seized by Iranian authorities under a false pretext,” the firm warned.

The EU-led mission, called the European Maritime Awareness in the Strait of Hormuz, did not respond to a request for comment.

Hours later, the British military’s United Kingdom Maritime Trade Operations, which also provides warnings to sailors in the Persian Gulf, issued its own alert.

“UKMTO have been made aware of an increased threat within the vicinity of Strait Of Hormuz,” the warning said. “All vessels transiting are advised to exercise caution and report suspicious activity to UKMTO.”

Iran’s state-run IRNA news agency cited this AP report without quoting any Iranian officials about it. Iran’s mission to the United Nations did not respond to a request for comment.

The Strait of Hormuz is in the territorial waters of Iran and Oman, which at its narrowest point is just 21 miles wide. The width of the shipping lane in either direction is only 2 miles. Anything affecting it ripples through global energy markets, potentially raising the price of crude oil.
