The Ukrainian government still has no idea about the full scale of sexual violence in the towns and villages that were occupied by Russians forces, she added.
“To calculate the number of sexual crimes is impossible at the moment because not everyone has come to us. Not everyone is willing to talk.”
More evidence of rape in the territories occupied by the Russians earlier in the war came to light on Tuesday.
Current Time, a Russian-language media outlet funded by Radio Free Europe, released a video of a middle-aged woman revealing that her daughter was raped in their village of Mala Rohan in the northeastern Kharkiv region.
She said her daughter, who was not identified, was picked off the street and raped by a Russian soldier at the local school.
“He took her to a classroom on the second floor and was raping her all night. He cut her cheek and neck,” she said.
The woman said her daughter was too distressed to speak to reporters directly.
The United Nations on Monday warned of an increased risk of sexual violence, calling for an independent investigation into the reports.
Sima Bahous, executive of the UN agency dealing with gender equality and women empowerment, said during an address at the Security Council that allegations of rape and sexual violence “must be independently investigated to ensure justice and accountability”.
