I remember 10k being the more frequently quoted number. But maybe that needs to be revisited - I was more naive about the degree of underreporting on ukrainian casualties. Maybe the truth is closer to 25k - which would make it comparable to Gaza. It will be difficult/impossible to know the real number given the reported cremations, the fact that the city is under Russian control, and that lot of the missing include residents who fled/were-transferred to Russia. The Gaza numbers are likely higher than official report given all the missing who are still under the rubble.
