Jailed Kremlin critic Alexei Navalny's anti-corruption group on Thursday vowed to continue its fight, hours after a court in Moscow branded it extremist and ordered it to stop working. "We woke up, smiled with destructive intent and knowing that we are a 'danger to society' will continue to fight corruption!" the Anti-Corruption Foundation (FBK) wrote on Twitter in response to the late-night ruling from the Moscow city court. jbr/mm/yad
