Ukraine’s President Volodymyr Zelensky has accused the Russian military of carrying out the worst crimes since World War Two.
He told the United Nations (UN) security council that civilians had been murdered and Russian tanks had crushed people “for pleasure”.
He called for those responsible to be tried as Nazis wer at Nuremberg.
Gruesome images of bodies lying in the street in towns such as Bucha have generated condemnation worldwide.
After his speech by video link to the Security Council, Zelensky showed a graphic video of images of dead Ukrainians, some burned and disfigured.
“The Russian military searched for and purposefully killed anyone who served our country,” he said.
“They killed entire families, adults and children, and they tried to burn the bodies.”
Russian UN Ambassador Vasily Nebenzia said there was no evidence Russian troops had carried out atrocities.
“We’ve heard once again a huge amount of lies about Russian soldiers and military,” he said. (BBC)
