The Yemeni Houthi group said on Sunday its forces had attacked two ships in the Red Sea and the Indian Ocean.

The first ship, Transworld Navigator, had been targeted in the Red Sea using "an uncrewed surface boat" which led to a direct hit against the ship, Houthi military spokesperson Yahya Saree said.

The second vessel, Stolt Sequoia, was attacked in the Indian Ocean with a number of cruise missiles, he said.

It was not clear when the attacks took place.
