Humanitarian conditions in war-torn east Ukraine regions controlled by Kiev government forces are of special concern, TASS News agency quoted the spokesman for the United Nations High Commission for Refugees while telling reporters on Tuesday.
Conditions in the northern part of embattled Donetsk and Luhansk were "particularly appalling" due to electricity and water shortages caused by shelling, the commission's spokesman William Spindler said.
"Of special concern was the situation in regions controlled by the Ukrainian government," Spindler said.
This was worsened by lack of access to allowances and services previously provided by the central government and notably by restrictions on the movement of people and goods, he added.
The number of internally displaced persons in Ukraine had reached 1.1 million and 674,000 people had found shelter outside their country.
