Ukraine's Zelenskiy urges Russians to 'go home'

STORY: Ukraine's assault comes after weeks of a stalemate in a war that has killed thousands, displaced millions, destroyed cities and caused a global energy and food crisis amid unprecedented economic sanctions.

It has also fueled worries of a radiation disaster being triggered by shelling near the south Ukraine Zaporizhzhia nuclear plant.

Zelenskiy, in his nightly address late on Monday, vowed that Ukrainian troops would chase the Russian army "to the border".

"If they want to survive - it's time for the Russian military to run away. Go home," he said.

"Ukraine is taking back its own," Zelenskiy said.
