Russian opposition leader Alexei Navalny has been detained just after being released from jail.

Mr. Navalny’s 30 days in jail for staging an unsanctioned protest ran out early on Monday. A police officer approached him and took him away just as he came out of a detention center in Moscow to be greeted by supporters and the media.
