Ukraine has lost up to 13,000 soldiers since the beginning of Russia's nearly 10-month-long unprovoked war, presidential adviser Mykhailo Podolyak said.
Mr Podolyak, a senior adviser to president Volodymyr Zelensky, on Thursday said the number is between 10,000-13,000.
"We are open in talking about the number of dead," he told Kanal 24 channel, adding that more soldiers had been wounded than had died.
