DUBAI, Sept 23, 2025 (BSS/AFP) - A British maritime security agency said an explosion was heard Tuesday near a vessel off Yemen, where Huthi rebels have been targeting shipping since the Gaza war began in 2023.

United Kingdom Maritime Trade Operations (UKMTO), run by the Britain's Royal Navy, said it "received a report of an incident 120 nautical miles east of Aden, Yemen".

It reported "splash and sound of explosion in the vicinity of vessel. Vessel and crew reported safe and proceeding to next port of call," it added.

There was no immediate claim of responsibility for the blast, which UKMTO described as an "attack".

The Iran-backed Huthi rebels, who have controlled large swathes of Yemen for more than a decade, have been attacking vessels they deem linked to Israel since soon after the Gaza war began with the Hamas attack of October 2023.

Earlier this month, the rebels said they had fired a missile at a tanker in the Red Sea, days after Israeli strikes killed their prime minister and nearly half of his cabinet.
