U.K. Defence Secretary Wes Streeting said the “continuing attacks” on the U.K.’s ally are “absolutely despicable.”

“The targeting of the airport in Riyadh in particular shows the lengths the Houthis are going to escalate the situation in the region,” he added, referencing the attacks earlier this month that killed 14 people and injured hundreds more.

Streeting said that the fighter jets will be used to protect Saudi airspace from drones and missiles. The U.K. will also send an Atlas A400M aircraft, used to transport the equipment, as well as military advisers.

“This builds on the UK equipment and personnel we already have in the country to defend against Houthi air attacks,” Streeting said.

The MoD argued that there is a link between the conflict in the Persian Gulf and the situation domestically in the U.K., pointing to disrupted energy supplies and a subsequent rise in the cost of living.

Since Prime Minister Andy Burnham arrived in Downing Street in July he has offered more support to Saudi Arabia. In September, he agreed to a request for air-to-air refueling of the country’s jets.

Pressed Tuesday on whether the U.K. risked being sucked into the Saudi war with the Houthis, Burnham’s official spokesperson told reporters: “I don’t accept that characterization. Our support for Saudi Arabia is considered proportionate and focused on helping them defend themselves against relentless Houthi attacks.”

They added: “Regional instability can have a serious impact at home in the U.K. We’re clear it’s in the U.K.’s economic and security interests that the Houthis do not succeed, and our approach is about defending our people, our interests, and our allies.”
