The northeastern Ukrainian region of Sumy has exchanged a captured Russian officer for five fighters from Ukraine’s defence forces, Governor Dmytro Zhyvytskyy says on social media, adding that it is the first such swap in the area.
He posted a video of a blond-haired man in handcuffs and wearing a green camouflage jacket, saying he was born in 1997 in the Russian city of Omsk.
He also said that he was being taken to be exchanged for Ukrainian fighters.
Reuters was not able to independently verify the video immediately.
Russian commanders have intensified their bombardment of Ukrainian urban areas in a shift of tactics on the sixth day of their assault.
Russia’s TASS news agency reported new peace talks between Russia and Ukraine would be held on Wednesday.
A first round of talks between Russian and Ukrainian officials on Monday at the Belarus border failed to reach a breakthrough.
