Here is a bit more from AP on the latest joint airstrikes:

US officials say the US and British militaries are bombing multiple sites used by the Iranian-backed Houthis in Yemen.

It is the second time the two allies have conducted coordinated retaliatory strikes on the rebels’ missile launching capabilities.

Officials say warship- and submarine-launched Tomahawk missiles and fighter jets were used to take out Houthi missile storage sites and launchers.

The joint operation comes about 10 days after US and British warships and fighter jets struck more than 60 targets in 28 locations.

US and British forces have conducted joint airstrikes targeting Houthi missile sites in Yemen for a second time.

The latest strikes came shortly after the White House said Joe Biden, the US president, had spoken to the UK prime minister Rishi Sunak, emphasising the need to continue “disrupting and degrading” Houthi military capabilities.

Three US officials confirmed the latest move against the Iran-aligned group over its targeting of Red Sea shipping, according to Reuters.

The US military denied claims that the Yemeni rebels had successfully targeted a US military support ship earlier in the day.

White House spokesman John Kirby said the US president had discussed the situation with the British prime minister on Monday, following continued Houthi attacks on shipping transiting the Red Sea and nearby Gulf of Aden over the past week.

“They talked about what’s going on in the Red Sea and the need for a continued international multilateral approach to disrupting and degrading Houthi capabilities,” Kirby told reporters in Washington, in an apparent reference to military action.
