Former world heavyweight champion Wladimir Klitschko posted graphic footage of dead, bound bodies in Bucha and accused Putin of 'genocide'

• A video posted by the former world champion boxer Wladimir Klitschko shows bodies in Bucha, Ukraine.
• "They've been shot in the head, with tied hands behind their back," he says.

Wladimir Klitschko, the Ukrainian former world heavyweight champion boxer, called the mass killings of civilians in Bucha, Ukraine, "genocide" in a video posted on Twitter on Sunday.

Klitschko, who is fighting in Ukraine's capital, posted graphic footage from Bucha, a town on Kyiv's outskirts, showing bodies of people he said were innocent civilians.

"I'm in the city of Bucha, on the outskirts of the capital. What happened here — and everywhere in Ukraine what is happening — this is not a special operation, this is not military objects, this is civilians," Klitschko says in the footage.

Klitschko then pans to the bodies on the ground. Blood can be seen under them.

"They've been shot in the head, with tied hands behind their back," Klitschko continues.

"This is genocide of the Ukrainian population, and that's exactly what the Russian regime, Putin's regime, Russian army, is doing, killing civilians with tied hands behind their back and with a shot in their heads."

Klitschko's sentiment echoed that of Ukrainian President Volodymyr Zelenskyy, who in an interview with CBS on Sunday accused Russia of war crimes and genocide.

"Indeed, this is genocide," Zelenskyy said. "The elimination of the whole nation and the people. We are the citizens of Ukraine. We have over 100 nationalities. This is about the destruction and extermination of all these nationalities."

Zelenskyy also posted photos on Telegram on Sunday showing dead bodies in Bucha.

"Mothers of Russian soldiers should see that. See what bastards you've raised. Murderers, looters, butchers," he said alongside the photos.

Bucha's mayor, Anatoly Fedoruk, said over the weekend that nearly 300 people had been buried in mass graves in the town, according to Agence France-Presse.

According to a CNN report, Fedoruk also told Reuters: "Corpses of executed people still line the Yabluska street in Bucha. Their hands are tied behind their backs with white 'civilian' rags, they were shot in the back of their heads. So you can imagine what kind of lawlessness they perpetrated here."
