Hall of Fame Ukrainian boxer Vitali Klitschko said he will take up arms to fight Russia as attacks on his homeland have continued.

Vitali said he will fight alongside his brother and former heavyweight champion Wladimir Klitschko, who enlisted earlier this month into the Ukrainian reserve army.

Vitali, 50, who is also the mayor of the capital city of Kyiv, told Good Morning Britain that Ukraine is already fighting a "bloody war" and he doesn't have "another choice."
