Dozens of People Detained in Moscow Protest

Moscow police have detained dozens of people at an anti-Kremlin protest, including several prominent opposition leaders.

Several hundred demonstrators shouting "Shame!" gathered Sunday in a central Moscow square, defying a ban imposed by authorities.

The protesters say their demonstrations are being banned in violation of the Russian constitution's guarantee of the right to gather.

Riot police quickly broke up the protest and detained several dozen demonstrators, including opposition leader Boris Nemtsov and Oleg Orlov, the head of the Memorial rights group.

Similar protests were held last year.

Russian authorities have shown little tolerance of dissent, banning most opposition rallies and sending riot police to detain protesters.
