To avoid Houthi attacks while traversing the Red Sea, some shipping companies have resorted to putting messages indicating their neutrality or willingness to fight as their destination.

The Houthis began their attack against maritime shipping in the Red Sea on Nov. 19 after declaring war on Israel, the first major expansion of the Israel-Hamas war. The attacks have ground shipping in one of the busiest trading arteries in the world to a halt, leading to a U.S.-led intervention.
