(Reuters) - Russian forces are undertaking a "massive redeployment" of troops to three southern regions of Ukraine in what appears to be a change of tactics by Moscow, a senior adviser to President Volodymyr Zelenskiy said on Wednesday.

Russian forces have taken over Ukraine's second biggest power plant, presidential adviser Oleksiy Arestovych said in an interview posted on YouTube. Russian-backed forces had earlier announced the capture of the Soviet-era, coal-fired Vuhlehirsk plant in eastern Ukraine.
