These bunkers are located in the separatists control zone so access for humanitarian organizations is possible but very difficult to organize in a war area.Some of the bunkers have electricity but most of them don't have any water system. So either humanitarian organization bring bottles of water or they run during the day to their houses to fill-up bottle. The walls of the bunkers have no finish on it so, a constant white dust from the cement is lying on beds, tables, or raise-up when you walk even if the families do their best to clean it up. Since end of cold war, these bunkers are not in use so the owners (coal mines, municipality, etc.) tolerate these squatters for humanitarian reasons.
