More than 11,000 Russian troops have been killed since Moscow launched an invasion of Ukraine on 24 February, the Ukrainian armed forces' general staff has said on Sunday.
A day earlier, it put Russian casualties at over 10,000. It did not report Ukrainian casualties.
Also on Sunday, the Ukraine port city of Mariupol, which is surrounded by Russian troops, said it will begin efforts to evacuate its civilian population, after earlier efforts were scuppered by ceasefire violations.
"From 1200 (1000 GMT) the evacuation of the civilian population begins," city officials said in a statement, which said a ceasefire was agreed with Russian-led forces surrounding the city.
While laying siege to Mariupol for days, Russian forces also cut its electricity, food, water, heating and transportation in the depths of winter, prompting comparisons to the Nazi blockade of Leningrad in World War II.
