KIEV, Feb. 5 – Kyivstar has switched off its mobile communications network in certain areas of Donetsk and Luhansk regions, citing improper usage of its network.

Kyivstar's press service told Interfax-Ukraine that at present it is impossible to control the network as some areas of Donetsk and Luhansk regions are temporarily not under the control of Ukrainian authorities. Kyivstar, observing Ukrainian law, taking into account security interests and the safety of client's data, temporarily disconnected the segment from the main network and suspended the provision of services to subscribers in the said territory. The state service for special communications and information protection of Ukraine, the Security Service of Ukraine and the National Commission for Communications Regulation were informed of the decision.
