Tens of thousands of protesters gathered in Russia over the weekend to demand the release of opposition leader Alexei Navalny. Navalny was detained last week after returning from Germany, where he was recovering after being poisoned with a nerve agent last August. Russian authorities arrested over 3,000 people during the protests on Saturday, prompting criticism from the US State Department (which called for the protesters to be released, citing human rights concerns).
More context: Navalny is the most prominent political opponent to President Putin.
Extra: The protests were planned across ~90 cities, with temperatures in some areas plunging to minus 58 Fahrenheit. Here’s a series of photos taken during the demonstrations.
