Biden warns Putin he cannot invade Ukraine or 'severe sanctions' will occur

Russian President Vladimir Putin warned President Joe Biden in a phone call on Thursday that relations between the two countries could collapse if the US imposes sanctions on Russia over its actions in Ukraine.

The Kremlin aide Yuri Ushakov said after the call that Putin told Biden that sanctions "could lead to a complete breakdown in ties between our countries," Reuters reported.

"Our president also mentioned that it would be a mistake that our descendants would see as a huge error," he said.
