In what appeared to be a clear indication of the mounting discontent over Vladimir Putin's 12-year reign, tens of thousands of Russians joined a massive wave of protests against the alleged rigging in the Dec 4 parliamentary elections.

According to agency reports, Moscow saw the biggest show of solidarity by protesters. People descended on Sakharov Avenue in thousands braving harsh wintry conditions. The protesters converged on a broad avenue which is just a couple of miles away from Kremlin.

The demonstrators are demanding a re-run of the parliamentary elections and also the prosecution of officials responsible for the alleged election rigging. "We want to back those who are fighting for our rights," Darya Andryukhina, a 16-year-old protester, told the Associated Press.
