“The level of brutality of the army of terrorists and executioners of the Russian Federation knows no bounds – raped children,” she wrote on Facebook.
“There is no place on earth or in hell where racist criminals can hide from retribution!”
She appealed to the UN Human Rights Commission to “take into account these facts of Russian war crimes in Ukraine.”
Senior UN official Sima Bahous told the Security Council on Monday that while all allegations must be independently investigated, “the brutality displayed against Ukrainian civilians has raised all red flags”.
“We are increasingly hearing of rape and sexual violence,” she said.
Russia’s deputy UN ambassador Gennady Kuzmin denied the allegations and accused Ukraine and allies of “a clear intention to present Russian soldiers as sadists and rapists.”
Russia’s defence ministry said Ukraine’s government was being directed by the United States to sow false evidence of Russian violence against civilians despite what it cast as Moscow’s “unprecedented measures to save civilians”.
International laws of war prohibit wilful killing, rape and other sexual violence, torture and inhumane treatment of captured combatants and civilians in custody.
Anyone who orders or deliberately commits such acts, or aids and abets them, is responsible for war crimes. Commanders of forces who knew or had reason to know about such crimes but did not attempt to stop them or punish those responsible are criminally liable for war crimes as a matter of command responsibility.
Investigators from the International Criminal Court are already working in Ukraine to gather and vet evidence, and a number of nations have already referred the case to the global court, signalling a strong push to bring such crimes to trial.
New reports of sexual violence also emerged on Tuesday morning AEST, with the BBC airing an interview with a 50-year-old woman who said she was raped at gunpoint in a rural neighbourhood about 70 kilometre west of Kyiv.
Named only as Anna to protect her identity, she said she was at home with her husband on March 7 when a foreign soldier barged in.
“At gunpoint, he took me to a house nearby. He ordered me: ‘Take your clothes off or I’ll shoot you.’ He kept threatening to kill me if I didn’t do as he said. Then he started raping me,” she said.
She said her attacker – a young, thin, Chechen fighter allied with Russia – was taken away by a separate unit of Russian soldiers when they discovered the crime. Her husband was shot in the abdomen and later died.
Andrii Nebytov, the police chief of the Kyiv region, told the British broadcaster about another case being investigated involving a couple in their 30s and their young child in a small village.
“On 9 March, several soldiers of the Russian army entered the house. The husband tried to protect his wife and child. So they shot him in the yard,” Nebytov said.
“After that, two soldiers repeatedly raped the wife. They would leave and then come back. They returned three times to rape her. They threatened that if she resisted they would harm her little boy. To protect her child she didn’t resist.”
