The russians declare it was ukrainian revenge killings of suspected collaborateurs. To help this, they convey a lot of arguments. Lots of the useless wore white armbands, signalling help for the russian military. Buch was taken about 4 days earlier than the ukrainians reported the bloodbath, throughout this time the mayor of bucha claimed that he was in bucha and that the russians had been routed, however didn’t point out any civilian casualties. So far as I do know, at leadt I’ve not heard anybody dispute this declare, right-wing paramilitary teams have been certainly among the many first to re-enter the village. Throughout the civil struggle they confirmed that they’re able to excessive brutality.
So its not completely not possible however there are different extra probably explanations.
Bucha was shelled extensively by the Ukrainian military and didn‘t have water or electrical energy for some time, russian troops have been in a good spot for a lot of days and sure needed to cope with partisan exercise. The variety of useless additionally appears too excessive for a revenge killing. Aswell because the state of decomposition of the corpses, which means that the ~300 useless have been killed over a lot of days and left our within the open for a while.
It appears extra more likely to me that inexperienced russian troopers misplaced their nerves.
