US President Joe Biden and Russia’s Vladimir Putin will speak via video call on Tuesday, the White House says, amid mounting tensions over Ukraine.
It comes after Secretary of State Antony Blinken said the US had evidence that Russia had made plans for a “large scale” attack on Ukraine.
But he added it was unclear if Mr Putin had made a final decision to invade.
Russia has denied any such intention, and accused Ukraine of executing its own troop build-up.
