Appearing in a wheelchair on Independence Square's main stage to a rapturous welcome from a 50,000-strong crowd, Tymoshenko said: "You are heroes, you are the best of Ukraine."
The fiery 53-year-old co-leader of the 2004 pro-democracy Orange Revolution then broke down in tears.
"Do not leave Maidan (Independence Square) as long as you have not obtained what you wanted," Tymoshenko told the crowd.
