ITV News correspondent Dan Rivers reports the latest in Ukraine as evidence of mass killings around Kyiv is revealed Vladimir Putin will have to face a war crimes trial following new allegations of atrocities committed by the Russian military, US President Joe Biden has said. His comments came after Ukrainian President Volodymyr Zelenskyy visited Bucha, one of the cities around Kyiv, where officials say the bodies of hundreds of civilians were found. Polish Prime Minister Mateusz Morawiecki, meanwhile, compared Putin to Hitler as he criticized French President Emmanuel Macron for negotiating with him as international leaders rounded up Russia. “You saw what happened in Bucha,” Biden said, adding that President Putin “is a war criminal.” The import of Russian gas and oil means that sanctions against Russia do not have the desired effect of isolation, says US correspondent Emma Muphy Zelensky called Russia’s actions “genocide” and called on the West to impose tougher sanctions on Russia, but Biden stopped using the same term. “We have to gather all the details to make it a reality – to have a war crimes trial,” Biden said. “What is happening in Bouha is outrageous and everyone sees it.” ITV News reporter Dan Rivers says he has seen three mass graves and adds all the evidence showing Russia The bodies of 410 civilians have been removed from cities in the Kiev region recently recaptured by Russian forces, said Ukraine’s Prosecutor General Iryna Venediktova. The allegations prompted the Polish prime minister to single out a number of leaders, including French President Emanuel Macron and German Chancellor Olaf Solz. “How many times have you negotiated with Putin? What have you achieved? Have you stopped any of these actions?” He asked Mr. Macron. “Criminals must not be discussed and negotiated. Criminals must be fought.” Tanya Nedashkivs’ka, 57, mourns the death of her husband who was killed in Bucha.

Speaking during a visit to Bukha, he said evidence of atrocities made it difficult to hold talks with Russia. “It is very difficult to negotiate when you see what they did here,” he said, adding that in Buha and elsewhere “they were found dead in barrels, underground, strangled, tortured.” He added that “the more she is carried away by the Russian Federation, the worse her situation will worsen and this war.” He also warned residents that Russian forces were creating a “catastrophic” situation for civilians, leaving mines around houses, abandoned equipment and even corpses. Amid calls for more action by Western nations, Germany has deported 40 Russian envoys to the Bucharest atrocity and said it was preparing further measures with allies as the United States plans to seek to suspend Russia from its headquarters in top UN human rights. body. What happened outside Kyiv? Ukrainian authorities say the bodies of at least 410 civilians have been found in areas outside the Ukrainian capital since Russian troops withdrew last week – many with their hands tied, gunshot wounds and signs of torture.

Some of the dead were buried by friends near their homes in marked graves, but many others were hastily trapped in mass graves, without tombstones or even identification. In one of his graves he was seen holding about 280 corpses in two rows – one side for dead Russians and the other for Ukrainians.

Locals said the dead were civilians killed without provocation, a claim that could not be verified by independent Russia has denied the allegations in a statement issued Friday stating “Similar, baseless allegations concerning Russia’s foreign policy have been made more than once. The country’s ambassador to the United Nations, Vassily Nebenzia, has dismissed the allegations as “fake news” – although his allegations are widely believed. “On April 4, the Kiev regime, with the active support of Western sponsors, began spreading fake news to the Western media about alleged atrocities by Russian military forces in the city of Bucha. “It was clear from the beginning that this was nothing more than a staged challenge aimed at devaluing and dehumanizing the Russian army and leveling political pressure on Russia.” What did the United Kingdom say? A spokesman for Boris Johnson said the bodies found in areas recently recaptured by Russia showed “abhorrent attacks on innocent civilians and further evidence that Putin and his army are committing war crimes in Ukraine”. But he stopped calling it genocide. The spokesman said that “the prime minister’s view is that Putin crossed the threshold of barbarism some time ago”, but added that only a court can rule on genocide. Britain urges Western allies to impose tougher sanctions to “intensify” pressure on Russia, including its complete severance from the international SWIFT payment system.
