The number of Russian casualties since the beginning of the full-scale invasion has passed half a million, Ukraine says.
More than 1,000 more were either killed or wounded in the last 24 hours.
While other Western estimates on Russian losses differ from Ukraine's, it is nonetheless a sign of the staggering human cost of the war for Moscow.
Russia does not routinely publish numbers of casualties or losses of equipment. Ukraine provides some figures but it does so infrequently.
In February, Volodymyr Zelenskyy said that 31,000 of his troops had been killed in two years of war.
