The official was quoting information from the UN Office for the Coordination of Humanitarian Affairs (OCHA).
"Humanitarian needs in areas under the control of armed groups are reportedly significant, with local organisations and Red Cross teams having nearly exhausted their supplies and with only limited amounts of aid having been delivered due to insecurity," Dujarric said at a daily news briefing here.
"Items such as winter clothing, shoes, medicine, and food are also in short supply," the spokesman said. "Some areas in the east have only limited or no access to drinking water and diesel generators are needed to power water pumps and treatment units."
According to the spokesman, the office of the High Commissioner for Human Rights will release a report on Ukraine in Geneva, Switzerland, Friday, which will cover the situation of Ukraine for the period from Aug 18 to Sep 16.
