The U.K. Ministry of Defense says four more Typhoon aircraft are scheduled to arrive in Qatar overnight and Royal Navy Wildcat helicopters have begun arriving in Cyprus.

British Prime Minister Keir Starmer announced the deployments on Thursday, part of a heightened security response after an Iran-linked drone attack on a British air force base on the Mediterranean island of Cyprus.

The helicopters are equipped with Martlet missiles that can counter one-way attack drones. The U.K. also plans to send a warship, the HMS Dragon, to the region next week.

The deployment of military equipment to the Middle East comes after an initial reticence about the unfolding war from the U.K. and other European allies, which were left out of planning for the U.S.-Israeli joint strikes over the weekend.
