The Biden administration was expected to announce plans to relist Houthi rebels as specially designated global terrorists, a U.S. official told Reuters. The U.S. military has carried out a series of strikes in Yemen against anti-ship ballistic missiles in a Houthi-controlled part of the country in response to attacks by the rebel group that have disrupted Red Sea shipping. The Iran-allied Houthi militia has threatened to expand its attacks to include U.S. ships in response to American and British strikes on its sites in Yemen.
