Police in Russia have arrested dozens of opposition activists who tried to rally in St. Petersburg today in opposition to the government of President Vladimir Putin.
Riot police with helmets, shields and body armor moved against demonstrators who were chanting "Russia without Putin!"
One of those detained was Boris Nemtsov, an opposition leader who is likely to be a contender in the presidential election next March.
The St. Petersburg crackdown on dissidents comes one week before Russia's parliamentary elections and a day after police detained other anti-government activists in Moscow.
An opposition member is calling the police action a "military operation." He says it shows that Russian authorities are afraid.
