Russian forces kept up a barrage of shell and missile attacks on various regions of Ukraine, many hitting power infrastructure, while heavy fighting persisted in the Luhansk and Donetsk regions in the east of the country.

As the winter’s first snow fell in Kyiv, authorities said they were working to restore power nationwide after Russia earlier this week unleashed what Ukraine said was the heaviest bombardment of civilian infrastructure of the war, which began on Feb. 24 when Russia invaded its neighbour.
