Kira Rudik, member of Ukrainian Parliament, spoke to GB News' Nigel Farage about accusations of Russian war crimes against civilians in Ukraine.
Ms Rudik, who was in Bucha earlier today, told Nigel Farage about her experience of the massacre after photos have emerged of bodies lying in the streets.
International outrage spread on Monday over civilian killings in northern Ukraine, where a mass grave and tied bodies of people shot at close range were found in a town taken back from Russian forces, as Moscow shifted the focus of the fighting elsewhere.
The Ukrainian MP said: "I have been to Bucha today with other parliamentary leaders. I have seen the mass grave. 300 bodies. I have never seen something like this before."
"They were peaceful people, mostly men but there were women and children with their hands behind their backs who didn't bare arms, who were sitting in their basements just waiting for the Russians to leave and they were executed just because they exist."

"We call it genocide. I have seen children who died of pneumonia because they had to in the basement for 39 days straight without the light of the sun."
Ukrainian President Volodymyr Zelenskyy said on a visit to Bucha "these are war crimes and will be recognised by the world as genocide". It had become harder, he said, for Ukraine to negotiate with Russia since the scale of alleged atrocities emerged.
Ms Rudik explained the horrific crimes committed by Putin's forces: "We have talked to women who were constantly raped by Russian soldiers with their children having to watch it. Women whose husbands were killed right in from of them and then they were severely raped."
"We have seen dead women's bodies who were raped beforehand and then the Russians tried to burn the bodies."
"We have seen people's bodies who were crossed over by tanks multiple times just for fun."
"We have seen so many crimes that you cannot forget it, you cannot understand how it is even possible. They killed people for the sake of killing," she explained.
The deaths in Bucha, outside Kyiv, are likely to galvanise the United States and Europe into additional sanctions against Moscow, possibly including some restrictions on the billions of dollars in energy that Europe still imports from Russia.
US President Joe Biden on Monday repeated his accusation that Putin was a war criminal and he called for a war crimes trial.
Putin "is brutal. And what's happening in Bucha is outrageous, and everyone's seen it," Biden told reporters.
