Ramzan Kadyrov, the head of Russia's republic of Chechnya, said on Sunday his soldiers have taken control of most of the eastern Ukrainian city of Popasna, while Ukrainian officials said a battle for the town in the east of the country is ongoing.
In mid-April, Russian forces launched a new offensive push along most of Ukraine's eastern flank, with some of most intense attacks and shelling taking place recently around Popasna in the Luhansk region.
