(QHA) -

Yulia Tymoshenko, leader of the Batkivschyna party and former prime minister of Ukraine, has called on law enforcement officials to react appropriately to the events in Donetsk, saying she is urgently leaving for the city, which is located in southeastern Ukraine, Interfax-Ukraine reports.

Tymoshenko said the events in eastern Ukraine are regarded as "a seizure by separatists", adding she is “confident that the Russian special services are involved in these events, reiterating that they are looking to annex the eastern part of Ukraine according to the Crimean scenario."

Tymoshenko has demanded that the authorities "take effective measures" and "prevent such events in the future."

Pro-Russia protesters have stormed government buildings in three major cities of Donetsk, Kharkiv and Luhansk in eastern Ukraine April 6.

Some protesters demanded a referendum like the one that resulted in the annexation of Ukraine's Crimea by Russia last month.
