Over 5,000 demonstrators were detained in major Russian cities Sunday, as authorities cracked down on people who defied orders and protested against the detention of opposition leader Alexey Navalny, monitoring groups said.
Why it matters: Navalny's detention has united Russians from a variety of backgrounds, including those who are against his politics, to protest the authoritarian leadership of President Vladimir Putin, per the New York Times.
Russian prosecutors have demanded that social media platforms censor calls to join protests, AP notes.
