Tensions in the maritime industry have escalated as Houthi forces detain multiple vessels at Yemen’s Ras Isa oil terminal, despite their United Nations clearance. Reports indicate that ships anchored in the area are being prevented from departing, with some forced to move from anchorage to berths inside the port.

Security Alerts & Threats

According to the UK Maritime Trade Operations (UKMTO), vessels in Ras Isa have reported threats of violence, including warning shots and armed boardings. The situation has been ongoing for two weeks, following a U.S. airstrike on April 17-18 that targeted the oil terminal. Yemen’s Ministry of Health confirmed 74 fatalities and 171 injuries, making it one of the deadliest strikes in recent months.

Ships & Crews Affected

Satellite data shows that at least a dozen oil tankers and several bulk carriers remain stranded. Among the affected vessels are ships linked to Russia and Turkey:

• Seven Pearls – A 53,714 DWT product tanker registered in St. Kitts and Nevis, sustaining minor damage during the attack. Three crew members were injured, one critically.
• St. Oslo – A Turkish-managed LPG carrier, registered in Panama, being held at the port with 17 Turkish sailors onboard.
• Unnamed Turkish Fuel Tanker – Carrying four Turkish nationals and 22 Indian crew members, the vessel suffered minor damage while unloading cargo but was denied departure.

Despite being cleared by the UN Verification and Inspection Mechanism (UNVIM), these vessels remain in limbo as Houthis refuse to allow them to leave.

Strategic Motives Behind the Detainment

Maritime security experts suggest that the Houthis’ actions may serve multiple strategic purposes:

Deterring military actions by the U.S., UK, and Israel. Reinforcing control over their ports to avoid appearing vulnerable.

Reports indicate that Houthi patrol boats have been actively monitoring the Ras Isa anchorage, increasing security risks for vessels operating in the region.

Regional Impact & Industry Concerns

The UKMTO warns that threats extend beyond Ras Isa, with ports such as Hodeida and Saleef posing significant security risks for vessels and crews. The situation follows over 800 U.S. military strikes in Yemen since March 15, 2025, aimed at securing safe navigation in the Red Sea.

As Houthis continue to exert control over commercial shipping, global maritime operators must remain vigilant.
