The US carried out further strikes against Iran-backed rebels in Yemen last night with the UK and America vowing to do what it takes to protect shipping in the Red Sea.
The latest strike, which the US said targeted a radar site, came a day after dozens of American and British strikes on the Iran-backed group's 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.
It followed joint air strikes from Britain and America the night before.

The Houthi movement's television channel Al-Masirah reported that the United States and Britain were targeting the Yemeni capital Sanaa with raids.
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.
Meanwhile, Britain's Defence Secretary Grant Shapps this morning told Iran to urge its allies to “cease and desist".

"We see you, we see through what you’re doing.
"We see how you’re doing it, particularly the Houthi rebels, and no good can come from it."
"Iran has an important part to play here and needs to understand that it needs to be clearer with its many proxies in the region that no good can come from this and everyone loses if they carry on going down this track," he added.
Foreign Secretary Lord David Cameron warned that allies would do “what is necessary” to “protect maritime freedom of navigation and important maritime pathways”.
He told NBC that the “very clear message” was that “if you act in this way there aren’t just warnings there are consequences”.
There were protest in Yemen on Friday as hundreds of thousands of people took to the streets chanting slogans denouncing Israel and the United States as they protested against the UK-US air strikes.
"Your strikes on Yemen are terrorism," said Mohammed Ali al-Houthi, a member of the Houthi Supreme Political Council. "The United States is the Devil."
