KIEV, Ukraine (AFP) — Protesters in Ukraine seized control of the capital Kiev and hailed freed Opposition Leader Yulia Tymoshenko in a historic turn of events yesterday, but marginalised President Viktor Yanukovych defiantly declared he still wielded power.

The situation in the ex-Soviet nation — deeply divided between aspirations towards the European Union and loyalty to Russia — was still fluid and uncertainty reigned over whether the Opposition had definitively triumphed over Yanukovych on a day of high drama exactly three months into the country’s crisis.

But there was clearly no more evidence of the brutal violence that had charred the heart of Kiev for much of last week and left nearly 100 people dead.

The tens of thousands of protesters who had occupied the city’s central Independence Square discovered that security forces had all but abandoned government and presidential buildings and that anyone was now free to enter unchallenged.

They and other city residents gaped in awe and anger at the ostentatious luxury Yanukovych had built up inside a private estate that featured everything from a private zoo to a replica galleon floating on an artificial waterway.

Yanukovych gave a television interview from the pro-Russian eastern bastion city of Kharkiv denouncing the “coup” against him and branding his political foes “bandits” — comments that won firm support from his backers in Moscow.

But the army issued a statement saying it “will in no way become involved in the political conflict” and the police force also declared itself in support of “the people” and “rapid change”.

The Parliament in Kiev stepped into the power vacuum left by Yanukovych’s departure by voting to oust the embattled president and setting new elections for May 25.

Lawmakers followed that up with an equally dramatic move ordering the release of Tymoshenko — a former premier and stalwart supporter of close EU ties who remained Yanukovych’s nemesis even when she was sent to prison in 2011 on a seven-year sentence for “abuse of power”.

“The dictatorship has fallen,” Tymoshenko declared in a statement on her release.

The fiery 53-year-old co-leader of the 2004 pro-democracy Orange Revolution, whose freedom had been sought strongly by both Washington and the European Union, waved to hundreds of supporters in Kiev after leaving prison.

The developments showed the balance of power in Ukraine swinging in the Opposition’s favour and seemingly superseding a Western-brokered pact Yanukovych had signed just a day earlier with the Opposition to resolve the country’s bloodiest conflict since its Independence in 1991.

The crisis erupted in November when Yanukovych dumped a pact promising closer ties with the European Union in favour of hewing closer to Soviet-era master Russia.

“This is a political knockout for Yanukovych,” charismatic former-boxer-turned-opposition-leader Vitali Klitschko said in a statement yesterday.

“Yanukovych is no longer president.”

Newly-elected Parliament Speaker Oleksandr Turchynov said Yanukovych “tried to take a plane to Russia but… was blocked in doing so by border police”. There was no immediate confirmation of that assertion.

But Yanukovych vowed flatly to fight any attempt to topple him.

“I am not leaving the country for anywhere. I do not intend to resign. I am the legitimately elected president,” the 63-year-old leader said in a firm voice.

Yanukovych added with a hint of outrage that “everything happening today can primarily be described as vandalism, banditry and a coup d’etat”.

Yet the president’s grasp on power appeared limited yesterday as government buildings stood without police protection and baton-armed protesters dressed in military fatigues wandered freely across his once-fortified compound.
