STORY: "Everyone in this hall, and everyone in the world knows that Russia and Russia alone, started this invasion," said Ukrainian envoy Sirgiy Kyslytsya.

"This war was not provoked. It was chosen by someone right now that is sitting in the bunker. We know what happened to the person who sat in the bunker in Berlin, in May, 1945."

The comment likened Putin to Adolf Hitler, the leader of Nazi Germany, whose aggression sparked the Second World War and who died by suicide in the ruins of Berlin just before the conflict ended.

Kyslystya drew further comparisons between the current conflict, which he described as a large power invading a smaller neighbor, and the start of World War Two.

"Does this remind you of something? Doesn't it?" he asked.

"And Russia's course of action is very similar to what their spiritual mentors from the Third Reich employed on the Ukrainian land, 80 years ago," he said.

Kyslytsya called Russian President Vladimir Putin's decision to put Russian nuclear forces on high alert, "a madness," again likening the Putin to Hitler by saying, "if he wants to kill himself, he doesn't have to use a nuclear arsenal. He has to do what the guy in Berlin did, in a bunker, in May, 1945."
