They have also stressed the overlap between conflicts there and in Ukraine, saying Russia has supplied Iran with drone parts and other support. Healey told a news conference that “Putin would want us to be distracted by the Middle East,” but Russia is the main threat to the U.K. and its allies. “We will not take our eyes off Putin,” he said.In late March, the U.K. said its military was ready to seize ships suspected to be part of Russia’s “shadow fleet” of vessels shipping oil in violation of international sanctions over Moscow’s war on Ukraine. Previously, Britain had only helped France and the U.S. monitor ships before they were boarded.“We are ready to take action” against the vessels, Healey said.
