Yemen’s Houthis said yesterday that they struck US and British ships in two separate attacks in the Red Sea, one of which was confirmed by a security firm.

In a statement, Houthi spokesperson of the Yemeni armed forces Yahya Saree said, “the first attack targeted the American ship Star Nasia, while the other targeted the British ship Morning Tide”.

British maritime security firm Ambrey had earlier reported that a UK vessel targeted and hit by UAV, the latest in dozens of incidents in the Red Sea.

The Barbados-flagged, British ship Morning Tide is a general cargo ship and the first UK vessel targeted by the Houthi group.

First major incident for U.K. affiliated vessels in the Red Sea, Ambrey said, adding that this is the first successful attack following several rounds of strike missions by coalition forces aimed at Houthi UAV and anti-ship missile launch sites.

The attack happened west of Al Hudaydah, in Yemen, and the projectile caused “slight damage” to the vessel’s windows on the bridge, the United Kingdom Maritime Trade Operations (UKMTO) reported. A small vessel had been nearby the ship before the attack, it added.

Until now the attack in the British ship has not been officially confirmed.

“The master stated that a projectile was fired at his vessel on the port side which passed over the deck, causing slight damage to the bridge windows,” United Kingdom Maritime Trade Operations said, without identifying the vessel or the flag it was flying.

“The vessel and crew are safe,” it added, saying the ship was proceeding on its voyage as planned.

Yemen’s Houthis have been harassing Red Sea shipping for months in protest against the Israel-Hamas war.

Their attacks have triggered reprisals by US and British forces, including a wave of airstrikes that hit dozens of targets late on Saturday.

The United States and the United Kingdom, with support from several other countries, have conducted extensive airstrikes on Houthi targets in Yemen, hitting over 30 targets across 13 different locations.

Saturday’s strikes marked the third time the US and Britain had conducted a large, joint operation to strike Houthi launchers, radar sites and drones. But the Houthis have made it clear that they have no intention of scaling back their assault.
