Protesters and police clash in Moscow
Riot police clashed with opposition supporters at the end of an anti-Kremlin protest in St. Petersburg, Russia, Sunday, beating some and hauling them into police buses.
Former world chess champion Garry Kasparov and several hundred other anti-Kremlin activists were detained after hundreds of riot police sealed off Moscow's Pushkin Square and clubbed some protesters to prevent a banned opposition rally and march.
It was not immediately clear what sparked the violence after the rally, which authorities in St. Petersburg had authorized and took place under a heavy police presence.
At the square earlier, lines of police, including undercover officers pointing out vocal demonstrators, quickly moved in on anyone who began to chant slogans or tried to galvanize people milling around the police cordon.
No information was immediately available on how many people were injured.
