Debaltseve, Donetsk region, is under control of the Ukrainian army, and the fighting for Vuhlehirsk continues, deputy head of the Ukrainian Interior Ministry's department in the Donetsk region Illia Kiva said.

"We are holding Debaltseve!!! There is fighting for Vuhlehirsk; half of the town is ours and fighting for the other half is fierce," he wrote on Facebook on Friday morning.

In his words, volunteer battalions of the police do not have enough ammunition and "the situation is serious but controllable."

In turn, Ukrainian parliament deputy (People's Front), Information Resistance Group leader Dmytro Tymchuk wrote on Facebook, citing operative reports, that the warring sides continued to exchange massive artillery fire on the perimeter of the Debaltseve sector over the past day.
