Kremlin critic Alexei Navalny called on his supporters Thursday to fight fear and continue pressuring the Russian authorities, in his first detailed comments since being ordered this week out to serve out a prison sentence. The 44-year-old anti-corruption campaigner wrote on Instagram that the authorities could only retain power if Russians remained afraid. "We, having overcome fear, can free our homeland from a handful of thieves in power. Let's do it. We must do it." jbr/txw
