Russian police on Saturday detained around a dozen anti-Kremlin opposition activists after they turned up near Red Square for a rally to support their jailed colleagues.
Police detained 13 out of around 30 activists who had planned to stage a rally in central Moscow, said Yekaterina Mochalova, one of the detained activists.
"We simply gathered near a monument when the police detained us," she told AFP from a police vehicle.
Some activists held placards with portraits of jailed activists, while one black-clad woman had a funeral wreath, a ribbon attached to it reading "Russian democracy," an AFP photographer reported from the scene.
Mochalova said that police chose not to detain a man who stood nearby with a placard reading "For Putin".
The activists, part of the leftist group the Left Front, had planned to hold a picket on Red Square, but police had cordoned it off.
The rally was planned in support of activists prosecuted for their participation in a May 6, 2012 rally, which turned violent one day before Vladimir Putin's inauguration.
Left Front leader Sergei Udaltsov is under house arrest until April 6.
Critics complain of a tough crackdown on dissenters after Putin returned to the Kremlin for a third term despite huge protests against his 13-year rule.
