Armed boats attempt to intercept vessel in Strait of Hormuz

Armed boats tried to intercept a vessel north of Oman on Tuesday in waters near the Strait of Hormuz, where heightened military activity and U.S.–Iran tensions are fuelling maritime security concerns.

United Kingdom Maritime Trade Operations (UKMTO) said the incident occurred about 16 nautical miles, or 29.6 kilometres, north of Oman, within the inbound Traffic Separation Scheme of the strait.

The agency said the vessel was approached by numerous small armed boats that attempted to make contact over VHF radio, requesting it to stop. The ship did not respond and continued on its planned route, prompting UKMTO to open an investigation.

The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea and is a critical route for crude shipments from Saudi Arabia, Iran, the United Arab Emirates, Kuwait and Iraq. Most of their exports pass through the narrow passage, primarily to Asia.

Tensions in the waterway have remained high in recent years. Three vessels were seized by Iran in or near the strait in 2023 and 2024. Some of those cases followed U.S. seizures of tankers linked to Iran, adding to friction over maritime security in the region.

Growing pressure in the Gulf

The attempted interception comes as the United States increases its military presence across the Middle East. Reutersreports that Washington has sent additional warships, including destroyers, to reinforce naval patrols amid heightened tensions with Iran. The deployments are aimed at deterring threats to commercial shipping and keeping key Gulf routes open.

Shipping patterns have already shifted. Dozens of vessels have been waiting offshore from Iranian ports in recent weeks as operators adopt a more cautious approach to Gulf transits. Maritime analysts say companies are adjusting routes and schedules as uncertainty builds around regional security.

Iran has also increased aerial activity. Defence officials report more frequent Iranian drone flights near sensitive maritime corridors, reflecting Tehran’s surveillance of shipping lanes. While no link has been made to Tuesday’s incident, the rise in drone activity adds complexity for vessels navigating the Strait of Hormuz.
