The United States and the United Kingdom launched new strikes on Houthi targets in Yemen on Monday, the second round of joint attacks on the group's camps in just over 10 days. 

The countries said the strikes were aimed at preventing the Houthi group from launching missile and drone attacks on commercial vessels in the Red Sea shipping lane.

On Monday, U.S. President Joe Biden and UK Prime Minister Rishi Sunak held a call and said they reiterated commitment to freedom of navigation, international commerce, and defending mariners from illegal and unjustifiable attacks. 

According to Houthi-run al-Masirah TV, Houthi camps in Yemen's capital and other provinces were hit at midnight Monday. Residents said the explosions were powerful and could be heard across the city. 

Monday's strikes came hours after the Houthis said they launched a missile attack at a U.S. military ship in the Gulf of Aden on Monday and claimed a direct hit. The U.S. side has denied the alleged attack.

The Houthi group has vowed to continue targeting ships linked to Israel in the Red Sea until Israel ends its war and blockade on Gaza, a Palestinian territory.
