U.S. Central Command (CENTCOM) confirmed that B-2 stealth bombers, which were equipped with 2,000-pound bombs, struck Iranian "hardened" ballistic missile sites.

The U.S. was cleared to use British bases for limited strikes on Iran’s missile capabilities on March 1 after Prime Minister Keir Starmer signed off on the plan, and while U.K. Defense Secretary John Healey stated Britain had "stepped up alongside the Americans."

Starmer said the authorization was granted to protect U.K. and U.S. allies as the conflict escalated. He had previously said he would not allow American forces to use U.K. bases for offensive operations in the region.

Tensions have since been heightened in the U.K. by security incidents in Cyprus. RAF Akrotiri, a key British military base on the island, was struck by a suspected drone on March 2, causing minor damage.

The unmanned aircraft was reported to resemble an Iranian-made Shahed drone, similar to models used by Russia in Ukraine and by Tehran’s regional proxies.

The Ministry of Defense said force-protection measures were at the "highest level" and that the base had taken steps to defend personnel. About 4,000 service members and their families are based at RAF Akrotiri.

The called Britain "uncooperative" and slammed Starmer as "not Winston Churchill" after Starmer initially rebuffed a U.S. request to use U.K. bases to attack Iran, according to The Associated Press.

Trump has also condemned Britain’s agreement to hand over the Chagos Islands, home to the Diego Garcia base, to Mauritius.
