KYIV, Sept 27 - Ukrainian authorities on Tuesday reported more success in their counteroffensive to reclaim territory in some of the very regions where Russia is staging the referendums to consolidate its grip.

Ukrainian troops claimed to continue their push beyond the Oskil River in the country’s east, pressing further into the Donbas.

A video on social media Tuesday showed Ukrainian soldiers entering the village of Koroviy Yar, 15 kilometers (about 9 miles) from the river, The Associated Press reported. Ukraine’s military intelligence said that the country’s forces continued to force Russian troops out of the northeastern Kharkiv region and claimed to recapture the major railway junction of Kupyansk-Vuzlovyi.
