The RF forces sieged Mariopol like a medieval city at the start of the war, creating large scale suffering. Afaik there was no water or power and people were melting ice for water.
The civilian casualties on the Ukraine war are at least 100,000+ maybe a multiple of that number.
Independent sources put it at 100,000+. I've randomly read 2x to 3x that but 100k+ is bad enough.

However, these are adults only, because children deaths are not counted at that time. With school-age children, for which records are stored, number raises to 10.5 million. Number of under school age children died because of artificial hunger in 1932-1934 is still unknown.
I hope, this will help to calculate number of deaths in Iraq.
It won't and there is not reason to think it will. It was a completely different situation. So keep your hopes to yourself.
