Opposition rally in Moscow draws tens of thousands

Tens of thousands of Russians flooded Moscow's tree-lined boulevards Tuesday in the first massive protest against President Vladimir Putin's rule since his inauguration in May - a rally that came even as police interrogated key opposition leaders.

Since embarking on his third presidential term, Putin has taken a stern stance toward the opposition, including signing a repressive new bill last week introducing heavy penalties for taking part in unauthorized rallies. (AP)
