The British military carried out airstrikes alongside the United States, targeting Yemen’s Houthi rebels, according to officials who announced the operation on Wednesday. This marked their first offensive in the intensified effort by Washington to combat the Iran-backed group.

Unlike the US, which has provided limited information on its airstrikes with over 1,000 targets hit since the campaign began on March 15, the United Kingdom offered a more detailed explanation for their participation in the strike.

Referred to as “Operation Rough Rider,” the campaign aims to weaken the rebels while the Trump administration engages in negotiations with Iran, the primary supporter of the Houthi rebels, to address Tehran’s advancing nuclear program.

UK strike hits near Yemen’s capital

The UK Defense Ministry described the site attacked as “a cluster of buildings, used by the Houthis to manufacture drones of the type used to attack ships in the Red Sea and Gulf of Aden, located some 15 miles south of Sanaa.”

Royal Air Force Typhoon FGR4s took part in the raid, dropping Paveway IV guided bombs, the ministry added.

“The strike was conducted after dark, when the likelihood of any civilians being in the area was reduced yet further,” the ministry said.

The British offered no information on the damage done in the strike, nor whether they believed anyone had been killed.

The US military’s Central Command didn’t acknowledge the strike.

“This action was taken in response to a persistent threat from the Houthis to freedom of navigation,” UK Defense Secretary John Healey said.

“A 55% drop in shipping through the Red Sea has already cost billions, fueling regional instability and risking economic security for families in the UK.”

The Houthis reported several strikes around Yemen’s capital, Sanaa, which the group has held since 2014.

Other strikes hit around Saada.

The British have taken part in airstrikes alongside the US since the Biden administration began its campaign of strikes targeting the Houthis back in January 2024.

However, this new strike is the first to see the British involved in the campaign under US President Donald Trump.

UK strike comes after US allegedly hit prison

The joint UK-US strike follows an alleged US airstrike on Monday that hit a prison holding African migrants, killing at least 68 people and wounding 47 others.

The US military said it was investigating.

On April 18, an American strike on the Ras Isa fuel port killed at least 74 people and wounded 171 others in the deadliest known attack of the US campaign.

The US is conducting strikes on Yemen from its two aircraft carriers in the region — the USS Harry S. Truman in the Red Sea and the USS Carl Vinson in the Arabian Sea, targeting the Houthis because of the group’s attacks on shipping in the Red Sea, a crucial global trade route, and on Israel.

The Houthis are the last militant group in Iran’s self-described “Axis of Resistance” that is capable of regularly attacking Israel.

The rebels began their attacks over the Israel-Hamas war in the Gaza Strip and the Israeli decision to block the flow of aid to Palestinians.

The American strikes have drawn controversy in the United States over Defense Secretary Pete Hegseth’s use of the unclassified Signal messaging app to post sensitive details about the attacks.

Early Thursday, Hegseth directly threatened Iran in a message on the social platform X.

“Message to IRAN: We see your LETHAL support to The Houthis. We know exactly what you are doing,” he wrote.

“You know very well what the US Military is capable of — and you were warned. You will pay the CONSEQUENCE at the time and place of our choosing.”
