Former boxing champs Wladimir and Vitali Klitschko say they're ready to fight for their home country of Ukraine - and are calling on the rest of the world to do the same.
- The brothers posted a video to social media on Friday in which Wladimir decried "this senseless war, which is not going to have any winners, but losers..."
- Vitali Klitschko is the mayor of Ukraine's capital city of Kyiv, while Wladimir enlisted in the Ukrainian reserve army three weeks ago as Russia began its military buildup.
- The Klitschko brothers are among the most successful heavyweight fighters ever, holding and defending all four major world heavyweight titles.
- Did you know Vitali Klitschko had a political career?
