The Houthi rebels targeted a U.S.-owned oil tanker in the Gulf of Aden amid the U.S. and the UK's fourth joint strike on 8 targets in 18 Yemeni locations. The USS Mason shot down one anti-ship ballistic missile likely targeting the oil tanker MV Torm Thor. The attack comes after the one on a British ship last week. The attack on vessel Rubymar sparked massive fire, causing evacuation from the ship. It also led to an 18-mile oil slick. Watch for more details.
