Eighty seven people were killed in a Russian air strike on the village of Desna last Tuesday, Ukrainian President Volodymyr Zelenskiy said on Monday during a speech to global business leaders at Davos.
Ukrainian authorities last week had said that eight people were killed in the strike on Desna, located in the northern Ukrainian region of Chernihiv.
Reuters could not immediately verify the new toll.
