KHARKIV, Ukraine — Ukrainian opposition leader Yulia Tymoshenko was freed on Saturday during the dramatic ouster of her arch enemy Viktor Yanukovych, setting up a possible run for the presidency in May.

Sporting her distinctive blonde braid, the 53-year-old former prime minister was driven out of the hospital in the northeastern city of Kharkiv where she had spent much of her confinement since 2011.

She waved to supporters, who chanted "Yulia, Yulia!"

"Our homeland will from today on be able to see the sun and sky as a dictatorship has ended," she told reporters.

"The dictatorship has fallen," Tymoshenko declared in a statement after her release. She also predicted further change now that she has been released.

"I am sure that Ukraine will be a member of the European Union in the near future and this will change everything," she was quoted as saying in Kiev

Tymoshenko's Fatherland party said she would go to Kiev's Independence Square, scene of nearly three months of protests against Yanukovych after he spurned a deal on closer ties with the European Union in favor of former Soviet master Moscow.

Seventy-seven people were killed in two days of carnage on and around the square this week.

Regretting the deaths of anti-Yanukovych protesters in gun battles and clashes with police, Tymoshenko said everything must be done so that "each drop of blood was not spilled in vain."

Tymoshenko was jailed in 2011 for abuse of office over a gas deal with Russia but her supporters and Western leaders regarded her as a political prisoner.

A fiery orator, Tymoshenko shot to fame during the 2004-5 Orange Revolution that overturned a rigged election won by Yanukovych. She became prime minister, but was forced out after Yanukovych beat her to the presidency in 2010.
