UK Maritime Trade Operations said it had “received reports of an attack on an MV [motor vessel]… approximately 23 nautical miles west of Ras Isa Marine Terminal”. The Saudi-led coalition identified the vessel as the UAE-flagged Rwabee, accused the Huthis of “piracy and hijacking” and indicated that the ship had been “carrying medical field equipment”. The Huthis maintained that it had “entered Yemeni waters without authorisation” and bore “clearly military equipment”. The U.S. denounced the seizure, calling on “the Huthis to immediately release the ship and crew unharmed and to cease all violence that sets back the political process to end the war in Yemen”.
