Intentionally targeting civilian areas with those bombs is a war crime. Ukraine avoids committing war crimes, Russia has committed many of them. There will be charges against Russia. There is even some evidence that Russia commits genocide: forced kidnapping of children, forced reeducation, some ethnic cleansing with deportations (though not very systematic), mass killings of civilians, and public speeches by government officials who deny Ukraine a right to exist and therefore can serve as proof of intent.
