No intention to deny individual episodes of war crimes, but the ratio of civilian to military casualties in the conflict is pretty low, despite a drawn out war and massive military casualties: we're talking about 12-15 thousand civilian deaths in almost four years of war. Absolutely tragic but doesn't seem to indicate a genocidal intent. Compare with the widespread massacres of civilians perpetrated by Israel in Palestine.
Ukranian civilians sensibly fleeing for their lives when the front gets close has prevented many deaths, and doesn't change the facts of what happens when they don't escape.
