US Central Command (CENTCOM) said on Wednesday its forces destroyed two Houthi radar sites in Houthi-controlled areas of Yemen in the past 24 hours. CENTCOM said the forces also destroyed two uncrewed surface vessels (USV) in the Red Sea. "It was determined the radar sites and USVs presented imminent threats to US, coalition forces, and merchant vessels in the region," it added. The Red Sea is one of the world's most frequently used sea routes for oil and fuel shipments. Earlier this year, US Defense Secretary Lloyd Austin announced a multinational mission, Operation Prosperity Guardian, to counter Houthi attacks.
