Ukraine's opposition parties are holding a rally in Kyiv to protest alleged rigging of the results from last month's parliamentary elections.
More than a thousand opposition supporters demonstrated on November 5 in front of the Central Election Commission headquarters.
Opposition parties -- including the Batkivshchyna (Fatherland) party of jailed former Prime Minister Yulia Tymoshenko and the Udar (Punch) party of former world boxing champion Vitali Klitschko -- are threatening to boycott the newly elected parliament.
With nearly all the votes counted, President Viktor Yanukovych's ruling Party of Regions and its allies appear to have retained a majority of more than 225 seats in the 450-seat parliament.
The Organization for Security and Cooperation in Europe called the election a step backward in Ukraine's democracy.
