(QHA) -

Ukrainian President and honorary member of the Party of Regions of Ukraine Viktor Yanukovych arrived in Kharkiv in the early hours of Saturday, a source with knowledge of the situation told, Interfax-Ukraine reports.

Yanukovych is supposed to take part in a congress of lawmakers from southeastern regions of Ukraine on Saturday, he said.

"This is what is planned, but the situation is changing rapidly. Changes are possible," the source said.

A high-ranking source from Yanukovych's entourage had said earlier in an interview with the ZN.UA that Yanukovych, accompanied by a narrow circle of especially trusted security guards, had flown to Kharkiv from Kyiv at 10:40 p.m. without stopping over at the suburban presidential residence of Mezhyhirya.

The source said Verkhovna Rada Chairman Volodymyr Rybak and presidential chief of staff Andriy Kliuyev were on the same plane with Yanukovych.

On Saturday, February 22, Kharkiv will host a congress of deputies of all levels of south-eastern regions, Sevastopol and Crimea.

The agenda of the congress has not yet been disclosed, but the opposition fears that a certain separatist scenario could be realized at the congress.

As we earlier reported, Ukrainian President announced early presidential elections, that are to be held in December 2014.

In Kyiv, antigovernment protesters rejected a peace deal signed by Yanukovych and opposition leaders on February 21, threatening instead to storm Ukraine’s presidential palace unless Yanukovych resigns by the morning of February 22.
