The powerful explosions in various parts of Ukraine began on Thursday morning and continue.

Former heavyweight champion Vitaly Klychko, now mayor of Ukraine's capital Kiev, says he has plans to fight to defend Ukraine from the Russian invasion.

"It's already a bloody war," said Vitaly Klychko, who also holds a seat on the Boxing Hall of Fame, on ITV's "Good Morning Britain" program.

The 50-year-old, who took over as mayor in 2014, has published a clip on Instagram where he stands with his brother Wladimir Klychko and talks about the invasion.

"Want to destroy the Ukrainian state"

"The war has no winner or loser.

I just want to say that we must stand united against Russian aggression.

Let it not happen in Europe, ”said the brothers, according to ESPN's translation.

Former Olympic heavyweight champion Wladimir Klychko writes about the events on LinkedIn according to ESPN:

"Now the Russian president is using war rhetoric.

He is clear that he wants to destroy the Ukrainian state and the sovereignty of the people. "

“Words are followed by missiles and tanks.

Destruction and death come upon us.

We will defend ourselves with all our might and fight for freedom and democracy ”.
