Biden said the images from Bhutto justified Putin as a “war criminal”, adding: “But we have to gather information. We must continue to provide Ukraine with the weapons it needs to continue the struggle. “We get all the details so that this is real – make a war crimes trial.” Biden’s assessment that the killings were not tantamount to genocide contrasts with that of Ukrainian President Volodymyr Zelensky, who used the term during a CBS interview on Sunday. “This guy (Putin) is brutal and what is happening in Bucha is outrageous and everyone has seen it,” Biden said. Pictures released this weekend show the bodies of civilians scattered on a street after Russian forces withdrew, and CNN reporters observed a mass grave in the city, with residents saying they believed at least 150 people were buried there. Scenes from the Kiev suburb Butsa has sparked international outrage, with Western leaders calling for war crimes investigations and new sanctions against Russia. US Secretary of State Anthony Blinken said on Sunday that the State Department would help document any attacks by Russian troops on Ukrainian civilians. NATO Secretary-General Jens Stoltenberg has described the deaths of civilians in Bhutan as “barbaric” and said “I warmly welcome” the International Criminal Court (ICC), which has launched an investigation into war crimes in Ukraine. The Russian Defense Ministry claimed that the extensive video of dead civilians in Bukha was “fake” and that “not a single local resident suffered violence” during the Russian occupation of the city. “In the settlements of the Kiev region, the Russian military personnel delivered and delivered 452 tons of humanitarian aid to civilians,” the ministry said in a statement.
