A leader of the protesters in the Ukrainian capital says they are in full control of the city after the signing of a peace deal aimed at ending the nation's three-month political crisis.
Media reports say that President Viktor Yanukovych has left the capital for his native eastern Ukraine after surrendering much of his powers and agreeing to early elections this fall.
The changes came as part of Friday's Western-brokered deal intended to end violence that killed scores and left hundreds wounded. The claims of his departure could not be immediately confirmed, however.
Andriy Parubiy, a leader of the protest camp on Independence Square, known as the Maidan, said Saturday that protesters are now in full control of the capital. Many of the protesters are continuing to demand Yanukovych's immediate ouster.
A spokeswoman for Yulia Tymoshenko, meanwhile, says the former Ukrainian prime minister and opposition icon has been released from prison.
Natasha Lysova told The Associated Press that Tymoshenko was released from her prison in Kharkiv on Saturday. She did not have further details.
Tymoshenko is the arch-rival of President Viktor Yanukovych and her arrest in 2011 and conviction on charges of abuse of office were widely seen as a case of political revenge.
