Ukrainian President Volodymyr Zelensky is calling for people around the world to join the fight against Russia.

In a statement on Sunday, he accused the Russian army of killing civilians and praised Ukrainians for having the courage to defend themselves.

"Ukrainians have manifested the courage to defend their homeland and save Europe and its values from a Russian onslaught. This is not just Russia’s invasion of Ukraine. This is the beginning of a war against Europe, against European structures, against democracy, against basic human rights, against a global order of law, rules and peaceful coexistence," Zelensky said.

Addressing "all citizens of the world, friends of Ukraine, peace and democracy," Zelensky said: "Anyone who wants to join the defense of Ukraine, Europe and the world can come and fight side by side with the Ukrainians against the Russian war criminals."

The statement added that those who wish to join should contact the Defense Attache of the Embassy of Ukraine in their countries.

Ukrainian Foreign Minister Dmytro Kuleba also echoed the call, tweeting Sunday:

"Foreigners willing to defend Ukraine and world order as part of the International Legion of Territorial Defense of Ukraine, I invite you to contact foreign diplomatic missions of Ukraine in your respective countries. Together we defeated Hitler, and we will defeat Putin, too."
