The UK-registered freighter Rubymar appears to be drifting north. New video shows him barely afloat after a Houthi attack.
Photos shared by authorities reveal its movements in the Red Sea over the past nine days.
The Belize-flagged vessel Rubimar was hit by a Houthi missile in the Bab al-Mandeb Strait on February 18. It has since moved about 70 km north.
A navigational warning to other ships in the area said the Rubimar was unmanned and moving in an unclear curve.
The ship's owner, Blue Fleet Group, told Sky News that the US Navy had offered to help tow the ship to the nearest port that would accept it, but added that negotiations were ongoing.
The Rubimar is carrying 22,000 tonnes of fertiliser, which is believed to be volatile.
Blue Fleet Group chief executive Roy Khoury said on February 26 that there was a "small fuel leak" which they were trying to fix before towing it.
The group is considering using a task ship to try to plug the hole caused by the Houthi missile.
The 24 crew members were forced to abandon ship on the day of the attack. The crew is from Syria, Egypt, India and the Philippines. They were rescued by the Djibouti Port Authority
Last week, the Houthis said they had sunk the ship. /BGNES
