Russian opposition leader Alexei Navalny is promising a campaign of civil disobedience against what he says was a stolen president election by Vladimir Putin. Mass protesting Navalny says tens of thousands will turn out for street protests in Russian cities and will keep up the protests until their demands are met. Police arrested Navalny and hundreds of other opposition supporters at an anti-Putin rally in Moscow Monday. He was later released. Many of the protesters chanted "Russia without Putin" and "Power to millions, not to the police." At the same time, thousands of Putin supporters rallied and waved the Russian flag outside the Kremlin. Putin wins election Prime Minister Putin won Sunday's presidential election by a landslide. European observers say the election was clearly skewed in Putin's favor. They also report voting irregularities at one-third of the polling stations. Putin calls the election an "open and honest struggle." World leaders acknowledge Putin's victory with reservations. European Union foreign affairs chief Catherine Ashton urged Russian leaders to address the "shortcomings" identified by international observers. The U.S. State Department congratulated the Russian people on the completion of the presidential poll and said it looks forward to working with the president-elect. But it also urged Moscow to launch an "independent and credible" investigation of all reported electoral violations. Observer assessment "What happened today, this experiment of [opposition leader Sergei] Udaltsov who tried to set up a tent camp, shows straight away that there are already hundreds of people who will stay until the very end. We will certainly stage mass protests, and thousands, tens of thousands people will come to the streets of Moscow and other cities and will refuse to leave. We will definitely do this, and we will be doing that until we win and achieve what we want,'' Navalny stated. "We would like to underline that, according to our assessment, these elections were unfair, despite some innovations in election process and unhindered possibilities for campaigning," said Tonino Picula, Head of OSCE Parliamentary Assembly Delegation and Former Croatian Foreign Minister: "We hope that the Russian authorities engage more energetically in complying with the OSCE commitments and expect that they will take these remarks as an incentive to engage in a process of electoral reform, thus allowing a genuine competition in future elections." "These elections were characterized by a number of the problems from the very beginning. The point of an election is that their outcome should be uncertain, this was not the case in Russia," Picula stated. .
