Yemen’s Houthi rebels vowed fierce retaliation Friday for American and British strikes against them, further raising the prospect of a wider conflict in a region already beset by Israel's war in Gaza. The bombardment — launched in response to a recent campaign of drone and missile attacks on commercial ships in the vital Red Sea — killed at least five people and wounded six, the Houthis said. The U.S. said the strikes took aim at more than 60 targets in 16 different locations across Houthi-controlled areas of Yemen.
