A cargo ship that was struck by a Houthi ballistic missile on Monday has created an 18-mile long oil slick in the Red Sea as it continues to take on water, two US officials said Friday.

The M/V Rubymar — a Belize-flagged, UK-registered, Lebanese-owned vessel — was carrying 41,000 tons of fertilizer when it was struck on Monday by one of two ballistic missiles fired from Houthi territory in Yemen.

US Central Command said the ship is currently anchored as it takes on water. “The Houthis continue to demonstrate disregard for the regional impact of their indiscriminate attacks, threatening the fishing industry, coastal communities, and imports of food supplies,” US Central Command said.
