Russia arrests over 4,500 at wide protests backing Navalny

Russian authorities mounted a massive effort to stem the tide of demonstrations after tens of thousands rallied across the country last weekend in the largest, most widespread show of discontent that Russia had seen in years. Despite threats of jail terms, warnings to social media groups and tight police cordons, the protests again engulfed cities across Russia's 11 time zones on Sunday. Navalny's team quickly called another protest in Moscow on Tuesday, when he is set to face a court hearing that could send him to prison for years.
