Yemen's Houthis targeted the Rubymar in the Gulf of Aden on Sunday, and it is now at risk of sinking, the group's military spokesperson Yahya Sarea said in a statement the following day.

"The ship is anchored but slowly taking on water," Central Command said in a statement regarding the Belize-flagged UK-owned cargo ship.

The Rubymar was transporting over 41,000 tons of fertilizer when it was attacked, the statement added.
