Iran warns UK letting US use bases is 'participation in aggression'

Iran's foreign minister has warned Britain that allowing the United States to use its military bases constitutes "participation in aggression," urging UK counterpart Yvette Cooper to halt such cooperation. The statement reflects Tehran's long-standing opposition to U.S. military operations in the region and signals Iranian displeasure with British alignment with American defense posture. Iran has historically viewed foreign military infrastructure in the Middle East as a threat to its regional interests and a potential staging ground for military action against Iranian targets. The warning underscores escalating tensions between Iran and Western powers, particularly as the Trump administration pursues a more assertive foreign policy in the region. Cooper's response and whether Britain adjusts its military arrangements with the U.S. will indicate the weight of Iranian pressure on London's strategic calculations.
