The United States and Britain struck dozens of targets in Yemen on Saturday in response to repeated attacks on shipping by Iran-backed Houthi rebels that have disrupted global trade and put lives at risk.

The joint air raids in Yemen come a day after a separate wave of unilateral American strikes against Iran-linked targets in Iraq and Syria that were carried out in response to the killing of three US soldiers in Jordan on January 28.

It is the third time that British and American forces have jointly targeted the Houthis and the United States has also carried out a series of air raids against them on its own, but the rebels' attacks have persisted.

Saturday's strikes hit "36 Houthi targets across 13 locations in Yemen in response to the Houthis' continued attacks against international and commercial shipping as well as naval vessels transiting the Red Sea," the United States, Britain and other countries that provided support for the operation said in a statement.

US Defence Secretary Lloyd Austin said the strikes "are intended to further disrupt and degrade the capabilities of the Iranian-backed Houthi militia to conduct their reckless and destabilizing attacks."

"Coalition forces targeted 13 locations associated with the Houthis' deeply buried weapons storage facilities, missile systems and launchers, air defense systems, and radars," he said in a statement.

Neither Austin nor the joint statement identified the specific places that were hit, but the Houthis' Al-Massirah television said Sanaa and other locations were targeted.

Meeting ‘escalation with escalation’

Britain's Defense Ministry said Royal Air Force Typhoon warplanes struck targets including two ground control stations used to operate both attack and reconnaissance drones.

Separately, US Central Command (CENTCOM) said its forces carried out a strike against a Houthi anti-ship missile "prepared to launch against ships in the Red Sea" early Sunday morning after deeming it "presented an imminent threat" against military and commercial vessels in the area.

That strike came after CENTCOM said they had earlier Saturday also launched strikes against six other Houthi anti-ship missiles and that on Friday US forces had shot down eight drones in and near Yemen, and destroyed four more before they could be launched.

Houthi spokesman Nasr Al Din Amer said, "We will meet the escalation with escalation."

The Houthis began targeting Red Sea shipping in November, saying they were hitting Israel-linked vessels in support of Palestinians in Gaza, which has been ravaged by the Israel-Hamas war.

US and UK forces responded with strikes against the Houthis, who have since declared American and British interests to be legitimate targets as well.

Houthi spokesman Nasr Al Din Amer said following the Saturday strikes that "either there is peace for us, Palestine and Gaza, or there is no peace and no safety for you in our region."

"We will meet the escalation with escalation," he wrote on social media.
