The Houthi rebel group has claimed that its naval wing has been successful in an attack against a Saudi-led coalition warship. The claim was made on social media.
A Houthi naval vessel apparently attacked the ship off the Red Sea coast of Mocha with a precision missile weapon system.
Apart from Saudi-coalition warships, the area is used by civilian cargo ships; their passage has been disrupted since 2015, due to Houthi military advances towards the south of Yemen.
The Houthis have targeted coalition ships along the Red Sea coast frequently. Unmanned explosive boats have been used in such attacks.
The Saudi-led coalition entered the Yemen civil war in March 2015 with the aim of reinstating President Abdrabbuh Mansur Hadi and preventing the Houthis from gaining a stronghold in southern Yemen.
