Ukraine claims more than 100,000 Russian soldiers have been killed in the war so far.
Kiev says that as of January 2, 107,440 Moscow soldiers have been killed, while 3,031 enemy tanks have been destroyed.
While Kiev and Moscow are reluctant to release casualty figures, in early December a senior Ukrainian official said up to 13,000 Ukrainian soldiers had been killed since the war began.
Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelensky, pointed out that between 10,000 and 13,000 troops had died – however, these figures were not confirmed by the Ukrainian military.
