TEHRAN — Iran’s Islamic Revolutionary Guard Corps (IRGC) has seized two foreign-flagged vessels in the strategic Strait of Hormuz, accusing them of entering its waters without authorization, in a move that has heightened regional tensions and drawn swift international concern.
Iranian state media said naval units intercepted the ships after they allegedly violated maritime regulations and ignored repeated warnings, before escorting them into Iranian territorial waters for further investigation.
“The security of the Strait of Hormuz is a red line,” an IRGC naval spokesperson said, according to state television. “Any vessel operating without proper authorization or engaging in suspicious activity will be dealt with in accordance with international and national law.”
The Strait of Hormuz, a narrow chokepoint between Iran and Oman, carries roughly a fifth of global oil supplies, making it one of the world’s most critical maritime routes. Any disruption is closely monitored by energy markets and major importing nations.
The incident comes amid renewed friction between Iran and the United States, driven by disputes over military activity, sanctions, and stalled diplomatic efforts. Tehran has repeatedly accused Washington of maintaining a “hostile posture” in the Gulf, including what it describes as sustained naval pressure.
U.S. officials condemned the seizures as “unjustified interference with freedom of navigation.” A spokesperson for the U.S. Navy’s Fifth Fleet, based in Bahrain, said coalition forces were “closely monitoring the situation” and called for the immediate release of the vessels.
“This kind of action threatens regional stability and undermines international maritime security,” the spokesperson said.
Shipping authorities and maritime organizations warned of increased risks for commercial traffic transiting the Gulf, a vital artery for global trade.
The International Maritime Organization urged restraint, calling on all parties to respect international law and ensure the safety of crews and cargo.
“We are closely following developments and stress the importance of de-escalation,” an IMO representative said.
Officials from the European Union also called for dialogue, warning against steps that could further inflame tensions.
“Freedom of navigation must be upheld, and all sides should avoid actions that risk escalation,” a European diplomatic source said.
Analysts cautioned that even limited disruption in the Strait could reverberate across global energy markets.
“Any instability in the Strait of Hormuz immediately feeds into price volatility,” said a regional energy expert. “Markets are highly sensitive to perceived risks in this corridor.”
Industry sources added that insurance premiums for vessels operating in the Gulf could rise sharply if tensions persist, increasing costs for global shipping and energy supply chains.
Iran has a history of detaining vessels in the Strait during periods of heightened confrontation with Western powers, often citing alleged legal or security violations.
The latest seizures highlight the fragile security environment in the Gulf and the strategic vulnerability of a waterway central to the global economy. They also risk complicating already uncertain diplomatic efforts between Tehran and Washington, where mutual distrust continues to overshadow prospects for de-escalation.
