Since 11 January, the US and UK have hit over 230 Houthi targets in Yemen – including attack boats, helicopters, air defence systems, and missile storage facilities. The US is also leading Operation Prosperity Guardian, a naval task force designed to step up policing in the Red Sea.

President Biden himself has said the strikes have failed to deter the Houthis and that he expects them to continue targeting vessels in the Red Sea. He has vowed to press ahead with the military campaign without providing an end date.
