Police officers are only maintaining public order at polling stations, and only on the nearby territory of district election commissions, the media liaisons office of the Ukrainian Interior Ministry's main office in Kyiv has reported.

"Law enforcement officers may enter the room where the votes are counted only at the invitation of the head, deputy head, secretary or by the decision of commission members in order to restore public order," the office said, while commenting on reports on the Internet that police officers allegedly do not allow subjects of the election process, observers and journalists enter the buildings of district election commission in Kyiv.

"The police are conducting pre-investigation checks into every complaint of citizens who, they say, were injured in clashes with unidentified people outside the buildings of district election commissions, including the use by unidentified persons of tear gas in some district election commissions," reads the statement.

The media liaisons office also said that police officers maintaining public order in the territories adjacent to election commissions had not used tear gas.
