Ukraine says between 2,500 to 3,000 of its troops have been killed, compared to Russia's 19,000

In an interview with CNN on Friday, Zelenskyy said the country has lost between 2,500 and 3,000 troops.

Zelenskyy said that out of the numbers they have, they think we lost between 2,500 and 3,000. It is hard to say how many of the injured will survive.

An anonymous NATO member estimated at the end of March that between 7,000 and 15,000 Russian troops had died in the conflict.

Zelenskyy was unable to estimate the number of civilian casualties since the towns and cities are blocked.

We don't know how many people have died in the area that is blocked on the east web.

The Office of the UN High Commissioner for Human Rights has recorded 4,232 civilian casualties in Ukraine so far but says the actual figures are considerably higher due to the blockades Zelenskyy described in parts of the country.
