Moscow warns US over Ukraine's new ability to strike Russian targets with long-range missiles

President Joe Biden has changed U.S. policy to allow Ukraine to use long-range missiles supplied by the U.S. to strike targets inside Russia. This decision has drawn strong warnings from Moscow and mixed reactions from Western allies. The policy shift comes as Russia continues its missile attacks on Ukrainian cities, resulting in civilian casualties. The U.S. had previously restricted Ukraine's ability to target Russian territory due to concerns about escalating the conflict. Russian officials have condemned the decision, claiming it escalates the war and threatens direct confrontation with NATO. Meanwhile, some NATO members support the change, emphasizing the need for unrestricted military aid to Ukraine.
