A senior Houthi leader said on Saturday he held British Prime Minister Rishi Sunak and his government responsible for the sinking of the UK-owned Rubymar.
Mohammed Ali al-Houthi, head of Yemen's Houthi supreme revolutionary committee, also said on X: "Sunak has a chance to recover the Rubymar by allowing aid trucks into Gaza."
Yemen's internationally recognised government said earlier on Saturday that the Rubymar, which was attacked by Houthi militants last month, had sunk in the Red Sea and warned of an "environmental catastrophe" from the ship's cargo of fertiliser.
