Houthi militias seized three ships, including one belonging to Saudi Arabia, three miles off Uqban island at the south end of the Red Sea, the group’s Al-Masirah TV said on Monday.
It did not identify the other ships but said all of them were taken to Salif port.
The Saudi-led military coalition fighting the Iran-aligned Houthis said earlier that the group had seized a vessel towing a South Korean drilling rig.
Coalition spokesman Colonel Turki al-Malki said in a statement carried by Saudi state media that the vessel was seized late on Sunday by armed Houthis. He did not say how many crew members were on board the ship.
Mohammed Ali al-Houthi, a senior Houthi official said the group’s forces had seized a “suspect vessel” in the Red Sea and that the crew were being treated well.
