mdd > How do you know that the buses can not go in because of the Russians,
1) because reps from international humanitarian organizations say so.
2) Buses stand in UKR-controlled area and are trying to go into RUS-controlled. UKRs who are surrounded inside the city are further down, they do not have access to the highway with RUS checkpoints.
Again, this is all for the courts. I am not sure why people are focused on atrocities. Start of the war was a despicable act by itself and should have been firmly opposed. Whatever RUS reasons were, no other country resolved to violence in Europe after WW2, outside of Balkan skirmishes, and Russians could have pursued other avenues even if they had some legit claim, such as cutting gas and blockading the coast.
