A U.K.-owned ship attacked by Houthi militants last month sank in the Red Sea, the U.S. military confirmed on Saturday, as it echoed a warning from Yemen's internationally recognized government that the vessel's cargo of hazardous fertilizer posed a risk to marine life.

The Belize-registered Rubymar is the first vessel lost since the Houthis began targeting commercial ships in November. Those drone and missile assaults have forced shipping firms to divert ships to the longer route around southern Africa, disrupting global trade by delaying deliveries and sending costs higher.

The sinking bulk carrier also "presents a subsurface impact risk to other ships transiting the busy shipping lanes of the waterway," U.S. Central Command (CENTCOM) said in its statement on social media platform X.
