Jailed Kremlin critic Alexei Navalny on Tuesday used the second anniversary of his incarceration to reinforce his promise to keep up his opposition, as his family and allies started a campaign to free him.
Navalny, 46, was arrested exactly two years ago as he returned to Russia from Germany, where he had been treated for poisoning with a deadly Soviet-era nerve agent in what he and some Western nations said was a Russian state assassination attempt. The Kremlin denied involvement.
