Moscow warns US over Ukraine's use of long-range missiles against Russia

Moscow has issued stern warnings following President Joe Biden's decision to allow Ukraine to use U.S.-supplied long-range missiles to strike targets in Russia. This marks a significant shift in U.S. policy after months of restrictions aimed at avoiding escalation. The change comes amid ongoing Russian missile attacks in Ukraine, which have resulted in civilian casualties. Kremlin officials claim that this new policy could dramatically alter the conflict, suggesting it implicates NATO countries in a direct confrontation with Russia. Ukrainian President Volodymyr Zelenskyy acknowledged the approval but emphasized that actions speak louder than words. Meanwhile, reactions from Western allies vary, with some expressing cautious optimism about the potential impact of the policy change.
