ADEN, Yemen — A tanker reported that a skiff chased it and tried to intercept it about 75 nautical miles east of Aden on Thursday, the United Kingdom Maritime Trade Operations said.
“A tanker travelling westbound has reported that a skiff has pursued and attempted to intercept the vessel,” the agency said in a post on X.
UKMTO said authorities were investigating. It logged the report as Warning 136-26.
The agency did not name the tanker, its flag or its operator. It did not say who was aboard the skiff, or how close the boat came.
No casualties or damage were reported. UKMTO gave no indication that the skiff reached or boarded the tanker.
UKMTO is the Royal Navy cell that collects reports from merchant ships in the Gulf of Aden, the Red Sea and the wider Indian Ocean. It relays warnings to commercial operators and to naval forces working in the region.
The account of Thursday’s incident rests on UKMTO’s advisory and on the master’s report to it. No independent confirmation has been published, and no party has claimed responsibility.
Skiff approaches are a recurring pattern in the Gulf of Aden. They can point to armed robbery at sea, to piracy, or to nothing at all, and UKMTO routinely treats such reports as suspicious activity until they are resolved.
The agency did not link the incident to any armed group.
The waters east of Aden lie at the mouth of the Gulf of Aden, outside the Bab al-Mandab strait. Ships bound for the Red Sea and the Suez Canal pass through them.
Maritime security reporting has described a resurgence of piracy off Yemen and Somalia this year, with separate accounts of cargo vessels approached by unidentified skiffs.
