"We have thousands upon thousands of civilians dead, it's a huge tragedy for our time as well as all of Europe.
"There are also tragedies that the Russian people don't understand, because they are affected and influenced by propaganda.
"Please do not believe the Russian propaganda. Please stop economic cooperation with Russia. It is all soaked into Ukraine blood.
"We are prepared to fight and defend our families, homes, and countries as well as principles and a way for life.
"We fight for all Europeans.
"Thank you everyone in Europe for your support. Sport can change the world, and we want to bring back peace to Ukraine and Europe.
Wladimir, the younger brother, added that "This is our most important fight."
"The greatest challenges of our lives are those we face."
Mothers and fathers in Ukraine are grateful for your assistance.
