The Crimean authorities plan to file claims against Ukraine for ceasing power supplies to the peninsula on Wednesday for two hours without any notifications, Crimea’s Deputy Prime Minister Dmitry Polonsky told TASS on Thursday.

The announcement comes as Ukraine, Dec 24, ceased power deliveries to Crimea, which is much dependent on power supplies from Ukraine.

Ukraine is confronting an energy crisis as supplies of coal from the belligerent Donetsk and Luhansk regions have been disrupted by the conflict there, and rolling blackouts in Ukrainian regions and in Crimea have occurred on several occasions.
