The sign reads: "We are against massive election fraud." Russians, angered by parliamentary elections they deem fraudulent, began a day of protests across the country Saturday in the biggest challenge yet to Prime Minister Vladimir Putin and the ruling United Russia party. The first protests Saturday began in the far east of the massive country. About 20 protesters were detained in the city of Khabarovsk. Moscow authorities gave permission for a rally on a square across the river from the Kremlin that brought together some 30,000 people later in the day. The protests follow an at times violent crackdown on a series of demonstrations earlier this week, after the United Russia party was declared the winner of parliamentary elections Sunday. The party barely held on to control the lower house, but opposition parties and observers contend the winning results were probably inflated. The protests come as Russia prepares to hold presidential elections in Match, which Putin, though weakened politically, appears to be set to win. They would return him to the country's highest office which, due to term limits, he was forced to relinquish five years ago. Thursday, Putin lashed out at U.S. Secretary of State Hillary Clinton because of her critical comments about the parliamentary vote. He accused Clinton of instigating protesters in order to weaken Russia. Some information for this report was provided by AP and AFP. .
