Multiple small vessels attacked a ship in the Red Sea near Yemen’s Al Hudaydah port, causing a fire on board and prompting the crew to abandon ship, UK Maritime Trade Operations said Sunday.

Crew members aboard a Liberian-flagged ship set ablaze by a series of attacks in the Red Sea abandoned the vessel Sunday night as it took on water, marking the first serious assault in the vital corridor for trade after a monthslong campaign by Yemen’s Houthi rebels there.
