MOSCOW, Aug 28 (Reuters) - A member of President Vladimir Putin's advisory council on human rights, Ella Polyakova, said on Thursday she believed Russia was carrying out an invasion of Ukraine.

"When masses of people, under commanders' orders, on tanks, APCs and with the use of heavy weapons, (are) on the territory of another country, cross the border, I consider this an invasion," Polyakova told Reuters. (Reporting by Gabriela Baczynska; Editing by Mark Trevelyan)
