In Russia, police violently broke up rallies and arrested more than 3,000 people in over 100 cities Saturday as protesters braved sub-zero temperatures to demand the release of nationalist politician and opposition leader Alexei Navalny. A rally in Moscow drew over 10,000 people — the biggest in years — with protesters chanting slogans against authoritarian President Vladimir Putin. Among those detained was Navalny’s wife, Yulia, and a prominent lawyer with the Anti-Corruption Foundation, who was arrested by riot police as she held a press conference.
