Meanwhile on the other side of the country civilians are also being killed and Russian propaganda is working on new excuses:

The Russian Armed Forces liquidated 93 Ukrainian deserters who fled from Mariupol in civilian clothes, said Colonel-General Mikhail Mizintsev, head of the Russian National Defense Control Center.
Not sure if they had the supposed deserters in custody, i.e. they executed prisoners of war, or they just shot at civilians from a distance, but either case sounds like an admission of a war crime.
Mariupol is a big separate story. Now Ukrainian marines are quite actively surrendering there, and Russian soldiers treat them within the framework of the Geneva Convention. However, in addition to the Marines, there are militants from Azov who play the role of detachments, and now they are not taken prisoner, and when they try to leave through the humanitarian corridor in civilian clothes, they are identified by Nazi tattoos and "denazified" on the spot.
