"Hello everyone from the police van," Navalny, an anti-corruption blogger, said on Twitter. At least one other protest leader was detained, witnesses at the scene said.

Riot police tried to disperse a group of protesters who remained on Moscow’s Pushkin Square, the scene of dissident demonstrations in Soviet times, after a rally calling for new elections and political reforms.

Protest leaders said about 20,000 people attended the rally. Police said 14,000 people attended.
