Investigations in Kherson, a recently liberated Ukrainian city, have revealed at least 20 torture centers with financial ties to Russia’s federal government, as stated by a group of international lawyers assisting Ukraine with probing alleged Russian war crimes.

A year after Russian troops seized the Ukrainian city of Kherson, new evidence has been presented. In November, Ukrainian forces regained control of the southeastern city, with a population of more than 280,000 people.

Wayne Jordash, the managing partner of Global Rights Compliance, informed CNBC that after working closely with Ukraine’s Office of the Prosecutor General, evidence of a financial connection between the main torture chambers in Kherson and the Russian state had been uncovered.

“Working closely with Ukraine’s Office of the Prosecutor General, a paper trail has been exposed that shows that the main torture chambers in Kherson and those administering them do so through the financial support of the Russian state.”
