What to know as Yemens Houthi rebels launch new attacks on ships in the Red Sea

Yemen's Houthi rebels have escalated Red Sea attacks, sinking two ships and killing crew members. This is a continuation of their campaign tied to the Israel-Hamas war. The Houthis, backed by Iran, claim to target ships to support Gaza. These attacks disrupt trade, and a prior US assault failed to diminish the Houthis' capabilities.
