MOSCOW—Russian President Vladimir Putin warned the West on Tuesday that NATO members in Europe were playing with fire by proposing to let Ukraine use Western weapons to strike deep inside Russia, which he said could trigger a global conflict.
More than two years into the deadliest land war in Europe since World War Two, Mr. Putin has increasingly spoken of the risk of a much broader global conflict as the West grapples with what to do about the advance of Russian troops in Ukraine.
