Ukrainian troops flooded into Kherson on Friday, liberating the southern port city after nearly nine months of Russian occupation—and clearing the way for some combatants to face accusations they aided the enemy. An Associated Press photograph taken on Sunday shows two alleged collaborators zip-tied to lampposts in the freshly liberated city, awaiting an unknown fate. Throughout the country in recent weeks, The Sunday Times of London reported, Ukrainian intelligence services have made a number of methodical arrests of assumed traitors, who are often held for weeks without charge. Ukrainian President Volodymyr Zelensky addressed the collaborators left behind by the Russian retreat on Friday, urging them to surrender under the guarantee they would “be treated in accordance with the law and international standards.” In a Sunday night video address, the president said that 400 instances of war crimes had already been documented in Kherson. Zelensky added that “the neutralization of saboteurs” remained an ongoing project for Ukrainian soldiers, with oblast governor Yaroslav Yanushevych claiming that the Russians had “mined nearly everything” as they pulled back, according to the Kyiv Independent.
