Ukraine's former prime minster Yulia Tymoshenko, a bitter rival of embattled President Viktor Yanukovich, arrived at a Kiev protest camp on Saturday after being freed from prison and warned that Ukraine couldn't be fully free until leaders took responsibility for their actions."You have the right to rule your own country!" she said, according to NBC News. Tymoshenko left the hospital in the northeastern city of Kharkiv, where she has been treated for a bad back while serving a seven-year sentence since 2011 on corruption charges. Parliament members had voted to free Tymoshenko after Yanukovych fled Kiev a day after announcing a deal with opposition leaders. He refused to resign Saturday and said he is traveling the country to seek advice and will “do everything to stop the bloodshed." Protesters seized Yanukovych's residence near Kiev on Saturday and opened the opulent property to the public and the media. Meanwhile, the White House welcomed Tymoshenko's release in a statement that promised to seek "a strong, prosperous, unified and democratic Ukraine."
