Jailed Russian opposition leader Alexei Navalny said on Wednesday that investigators had opened what he called an "absurd" terrorism case against him that could see him sentenced to an additional 30 years in jail.
Navalny, a former lawyer who rose to prominence by lampooning President Vladimir Putin's elite and alleging vast corruption, is serving combined sentences of 11-1/2 years for fraud and contempt of court on charges that he says were trumped up to silence him.
