Wladimir and Vitali Klitschko have posted a video on social media, calling for action from around the world to stop what they described as Russian aggression in their country.  

'This senseless war is not going to have any winners, but losers,' said Wladimir Klitschko, who has reportedly enlisted in the Ukraine army. 'Don't let it continue happening in Ukraine, don't let it happen in Europe and eventually in the world. United we are strong. Support Ukraine.'

Vitali Klitschko, who is the mayor of Kyiv, has declared a state of emergency and called on the city's 3 million people to stay indoors unless they work in critical sectors
