Russian forces have captured Ukraine's second biggest power plant and Moscow is undertaking a "massive redeployment" of troops to three southern regions, a senior adviser to President Volodymyr Zelenskiy said on Wednesday.
Russian-backed forces had earlier announced the capture of the Soviet-era, coal-fired Vuhlehirsk power plant.
"They achieved a tiny tactical advantage - they captured Vuhlehirsk," presidential adviser Oleksiy Arestovych said in an interview posted on YouTube.
