Zelenskiy hits back as Elon Musk sets up Twitter poll on annexed areas of Ukraine

Outrage and condemnation over billionaire's suggestions including formally making Crimea part of Russia

Elon Musk has prompted an online row with Ukraine's president after he asked Twitter users to weigh in on his ideas to end Russia's war.

In a tweet, Musk suggested UN-supervised elections in four occupied regions that Moscow has falsely annexed after what it called referendums. The votes were denounced by Kyiv and western governments as illegal and coercive. Russia leaves if that is will of the people," Musk wrote.
