Ukrainian President Volodymyr Zelenskyy has posted an Instagram video from his office to reassure Ukrainians that he is well after a spread of fake news concerning his health was circulated by Russian hackers. The comments came days after Russian officials dismissed claims that Russian President Vladimir Putin is suffering health-related issues.

"Today, Russia launched more fake news that the (Ukrainian) state is not controlled by President Zelenskiy as he is in hospital, or rather, in intensive care because of a 'serious health condition'.

So, here I am in my office, and I have never felt as good as now. And the bad news for those behind such fakes is that I am not alone. There are 40 million of us (Ukrainians)."

President Volodymyr Zelenskyy said.

In what is being said to be a dig at Vladimir Putin’s age, Zelenskyy added, "And with all due respect to old age, 44 is not (almost) 70."
