Over 3,000 supporters of Russia's Communist Party gathered in the center of Moscow on Sunday to protest against the alleged mass election fraud at the December 4 parliamentary elections.
"The rally organized by the Communist Party was attended by about 3,300 people, including media representatives," the Moscow police press office said, adding that the action was held without any incidents.
The protesters demanded a re-run of the parliamentary elections, the sacking of Central Election Commission chief Vladimir Churov and the replacement of the political elite.
The December 4 elections were marred by widespread allegations of fraud in favor of United Russia, with dozens of video clips appearing to show ballot-stuffing uploaded onto the Internet.
The ruling United Russia party won the December 4 State Duma elections, gaining about 50 percent of the vote. In the first few days, thousands went to the streets across Russia to protest the vote results, which they claimed were falsified.
