The United States and Iran-backed Houthi rebels in Yemen are both vowing escalation after the U.S. launched airstrikes to deter the rebels from attacking military and commercial vessels on one of the world's busiest shipping corridors.

Yemen’s Houthis have proven resilient to a months-long military campaign, spanning the Trump and Biden administrations, to halt the group’s attacks.

Houthi said his militants would continue to target American ships in the Red Sea as long as the U.S. attacks Yemen, warning, 'If they continue their aggression, we will continue the escalation.'
