WASHINGTON/MOSCOW (Reuters) - U.S. President Joe Biden warned Russian President Vladimir Putin on Tuesday the West would impose "strong economic and other measures" on Russia if it invades Ukraine, while Putin demanded guarantees NATO would not expand further eastward.

The two leaders held two hours of virtual talks on Ukraine and other disputes in a video call about U.S.-Russian relations, which have sunk to their lowest point since the end of the Cold War more than three decades ago.
