The United States carried out an additional strike against Yemen's Houthi forces on Friday, after President Joe Biden's administration vowed to protect shipping in the Red Sea.
The latest strike, which the US said targetted a radar site, came a day after dozens of American and British strikes on Houthi facilities.
The guided missile destroyer Carney used Tomahawk missiles in the follow-on strike early on Saturday local time "to degrade the Houthis' ability to attack maritime vessels, including commercial vessels," the US Central Command said in a statement on X.
The Houthi movement's television channel Al-Masirah reported that the United States and Britain were targeting the Yemeni capital Sanaa with raids.
Intensifying concerns about a widening regional conflict, US and British warplanes, ships and submarines on Thursday launched missiles against targets across Yemen controlled by the group, which has cast its maritime campaign as support for Palestinians under siege by Israel in Gaza.
Even as Houthi leaders swore retaliation, Biden warned on Friday that he could order more strikes if they do not stop their attacks on merchant and military vessels in one of the world's most economically vital waterways.
"We will make sure that we respond to the Houthis if they continue this outrageous behaviour," Biden told reporters during a stop in Pennsylvania on Friday.
Witnesses confirmed explosions early on Friday, Yemen time, at military bases near airports in the capital Sanaa and Yemen's third city Taiz, a naval base at Yemen's main Red Sea port Hodeidah and military sites in the coastal Hajjah governorate.
White House spokesperson John Kirby said the initial strikes had targeted the Houthis' ability to store, launch and guide missiles or drones, which the group has used in recent months to threaten Red Sea shipping.
The Pentagon said the US-British assault reduced the Houthis' capacity to launch fresh attacks. The US military said 60 targets in 28 sites were hit.
Drone footage on the Houthis' Al-Masirah TV showed hundreds of thousands of people in Sanaa chanting slogans denouncing Israel and the United States.
