A Russian court on Monday sentenced Kremlin critic Alexei Navalny to 15 days behind bars after ruling he had resisted police during an anti-corruption protest Sunday in Moscow.

Judge Alesya Orekhova at a district court in Moscow said Navalny was "guilty" and would spend 15 days in jail, and also fined him for holding the unauthorised rally that drew thousands to Moscow city centre, an AFP correspondent in the courtroom said.
