Yemen’s Houthi movement claimed a Sunday attack on the British-registered cargo ship Rubymar in the Gulf of Aden, which forced crews to abandon ship. The stricken vessel is now reportedly at risk of sinking. This comes after U.S. forces launched more retaliatory attacks on Houthi-controlled areas in Yemen over the weekend. U.S. Central Command confirmed Sunday at least five Houthi targets were struck, including an unmanned underwater vessel in the Red Sea and several missiles, which military officials claimed presented “an imminent threat to U.S. Navy ships and merchant vessels in the region.”
