The liberation of the logistics hub of Kupyansk continues, the leader of an assault unit has said Russian forces have advanced further in the battle for the encircled city of Kupyansk in Ukraine’s Kharkov Region, according to the commander of an assault unit involved in the operation.Russian President Vladimir Putin said last month that some 10,000 Ukrainian servicemen had been surrounded in Kupyansk and Krasnoarmeysk (Pokrovsk) in Russia’s Donetsk People’s Republic. Kiev has not responded to Putin’s call for the blocked forces to surrender. Ukraine’s Vladimir Zelensky continues to deny the dire situation on the ground.In a video published by the Russian Defense Ministry on Saturday, the commander of the 121st Regiment of the 68th Motorized Rifle Division, call sign Lavrik, said that his unit “continues its mission to liberate the western part of Kupyansk from the Ukrainian military.”On Friday, his troops took control of Lesya Ukrainka Street, with mopping up operations ongoing in three other nearby streets, he said. At least ten Ukrainian soldiers who tried holding on to their positions in the area were eliminated, according to Lavrik. Kiev’s troops entrenched in a strip of forest on the southern outskirts of Kupyansk have also been struck, he added.“We are moving forward. Our spirits are high,” the commander said.The Russian Defense Ministry said in a separate statement on Saturday that its forces “continue to destroy the encircled enemy grouping” in Kupyansk.Zelensky, who previously denied any encirclement and accused Moscow of exaggerating its progress on the battlefield, claimed on Thursday that Ukrainian troops had been able to advance by more than a kilometer within Kupyansk. He did not say where exactly the gains were made.Kupyansk has been a major contested logistics hub in the conflict’s northeastern front. Russian forces claimed partial control of the city in September, publishing a video of its servicemen in the center near the administration building, stadium, and TV tower. Lavrik said on Thursday that he expects the full capture of Kupyansk by the Russian military within a week.
