Russian police detained more than 1,700 people participating in protests on Thursday against Moscow's invasion of Ukraine, according to OVD-Info, a Russia-based human rights organization that monitors political persecution in the country.
Why it matters:Hundreds of people organized in multiple Russian cities — including Moscow and Saint Petersburg — for protests despite warnings from the government that participants would be arrested.
According to OVD-Info, demonstrators in more than 50 cities were detained.
The anti-war demonstrations are the largest organized protests against the Russian government since the Kremlin arrested Russian opposition leader Alexey Navalny last year.
The big picture: Thousands of people around the world participated in demonstrations rebuking Russia's unprovoked invasion of Ukraine on Thursday.
