Ukraine says two of its soldiers have been killed in the country's east as heavy fighting between government forces and Russia-backed separatists entered its fifth day.
The military said on February 2 that 10 other servicemen were wounded in the previous 24 hours.
Ukrainian officials had reported the deaths of eight soldiers in the past few days, the highest casualty toll in weeks.
In the separatist-held provincial capital of Donetsk, separatists said two civilians were injured by shelling late on February 1.
The sides traded blame for the surge in hostilities that are concentrated around the government-controlled city of Avdiyivka, where shelling left many residents without electricity, water supplies, and heating in temperatures well below freezing.
By February 2, the water supply and heating in the town north of Donetsk has been partially restored, the Associated Press reported.
More than 9,750 people have been killed in the conflict in eastern Ukraine since April 2014.
