Russia went to the UN and asked for an independent UN investigation. UK vetoed it, supported by the US. That says a great deal about who wants the truth to come out about Bucha.

Satellite images from March show that there are basically three sets of bodies. Two groups from 11 March and 19 March, when shelling of Bucha took place. The third group, the one with hands tied and head shots with fresh blood, this group only appears AFTER Russia left and the Azov National Guard group came in.

There is video evidence - provided by Ukrainian soldiers in Bucha - that UA forces are killing anyone not clearly on their side.

So we don't know yet who killed the people around 1 April, but the evidence so far does NOT lead clearly towards Russia committing the executions. Just the opposite.
