In Russia, at least 800 people were arrested Saturday as protesters took to the streets of Moscow again to call out the barring of opposition candidates in upcoming city council elections. Videos of police beating protesters with batons spread on social media over the weekend. Police also reportedly made arrests before the protests even started.

Meanwhile, opposition leader Alexei Navalny, who was arrested last month ahead of mass protests, is being investigated for money laundering. Navalny’s anti-corruption group has worked to expose top Russian officials. He was hospitalized last weekend, when his doctor said Navalny appeared to have symptoms of poisoning — but Navalny has since been returned to jail.
