Ukrainian President Petro Poroshenko has issued a decree that dissolves the country's parliament (Verkhovna Rada).
"I have decided to terminate the powers of the Verkhovna Rada early," Poroshenko said on his Twitter account.
The Ukrainian president's Facebook account announces that snap parliamentary elections have been set for October 26.
Poroshenko was quoted as saying by his press secretary, Svyatoslav Tseholko, that "the fifth column consists of a dozen so-called deputies, who obviously do not represent the interests of the people who elected them."
"And the majority of these deputies passed dictatorial laws that took the lives of "Heaven's Hundred", and someone has to take responsibility for this," the Ukrainian leader said.
"The president called on all democratic political forces to take part in these elections as a united, pro-Ukrainian and pro-European team," Tseholko said on his Twitter page on Monday evening.
Ukraine's parliamentary coalition, which formed a national government in March 2014, collapsed in mid-July after the UDAR and Svoboda factions pulled out of it.
The Ukrainian constitution permits the president to dissolve parliament and order early elections if a parliamentary coalition collapses and a new one fails to appear within the next 30 days.
