CNN —The commander of Ukraine’s eastern Donetsk group of forces has been replaced following Russian advances in the region, a military official said Saturday. The move comes after Lutsenko faced heavy criticism for failing to stop recent Russian advances on the key city of Pokrovsk. Russian forces have been spotted just three kilometers (1.9 miles) from the city, according to Ukrainian mapping service DeepState. Its fall to Russian forces would mark the largest setback for Ukraine in months and compound Ukraine’s struggles to get off the backfoot while Russian troops pile severe pressure on the eastern front lines. He added that Ukraine had information that North Korean soldiers may be being used along other parts of the front line.
