WILMINGTON, Del. (Reuters) -President Joe Biden said on Friday he told his Russian counterpart Vladimir Putin that a move on Ukraine will draw sanctions and an increased U.S. presence in Europe, where tensions are high after Russia's military buildup at the border.

The U.S. and Russian leaders exchanged warnings over Ukraine in a 50-minute call on Thursday to address Russian military actions.
