MOSCOW (Reuters) - Russian opposition leader Alexei Navalny was detained soon after joining a rally in Moscow on Sunday, the anti-corruption activist wrote on Twitter.


Hundreds of his supporters joined a nationwide day of protest against the authorities on Sunday, calling on voters to boycott what they said would be a rigged presidential election on March 18.
