Russia’s overnight bombing of regions in eastern Ukraine killed at least one, officials said on Sunday after Moscow ended a self-declared Christmas ceasefire and vowed to fight on until it defeats its neighbour. 

Two thermal power plants were damaged by Ukrainian shelling in Russian-controlled parts of the country’s Donetsk region with preliminary reports of injuries, Moscow-installed officials said on Sunday.  Serhiy Haidai, governor of Luhansk in eastern Ukraine, said on TV on Sunday there was heavy fighting in the region and Russian forces had deployed their most combat-ready units and heavy equipment to the city of Kriminna that they occupy, which he said meant the Russians were slowly retreating in the region.
