Couple of things:
The evacuation of civilians basically failed. First, the buses got stuck and had to wait due to nearby mortar shelling, then only 3 buses (out of 20) were filled with refugees, nobody else wanted to leave and, considering the risks, I don't blame them. This is a terrible thing to say, but not boarding these buses today was the prudent thing to do (today, the junta forces fired at refugees near Lugansk).
Now take a look at this map from militarymaps:
