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

President Joe Biden has changed U.S. policy, allowing Ukraine to use long-range missiles supplied by the U.S. to strike targets inside Russia. This decision has drawn strong warnings from Moscow, which claims it escalates the conflict. 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 tensions with NATO. Ukrainian President Volodymyr Zelenskyy acknowledged the change but emphasized that actions speak louder than words. Meanwhile, Russian officials have condemned the decision, warning it could lead to a direct conflict between NATO and Russia.
