Most of the 300 protesters detained on Monday at a demonstration in downtown Moscow against alleged electoral fraud remain in custody as of Monday morning, police said.
Two rally leaders, anti-corruption blogger Alexei Navalny and opposition activist Ilya Yashin, were delivered to court on Tuesday morning, said Navalny’s wife, Yulia, in a Twitter blog. Both face up to 15 days behind bars for refusing to obey police orders.
The demonstration - the largest opposition rally for many years in Moscow - was called to protest alleged violations during Sunday's parliamentary polls, in which Prime Minister Vladimir Putin's United Russia party just managed to hang onto its majority.
