Russia arrests over 4,500 antiwar protesters Sunday

Police in Russia arrested as many as 4,500 people Sunday in nationwide protests over President Vladimir Putin's invasion of neighboring Ukraine, according to multiple news reports.

The outcry is a remarkably brazen considering such public opposition is subject to a prison sentence. 

"No to war!" and "Shame on you!" protesters chanted in videos on social media.

The country's interior ministry reportedly said most of the arrests were in the capital city of Moscow and that 750 in St. Petersburg, another larger Russian city. 

The country is cracking down on dissidents, even in regions as remote as Siberia, in which a handful of arrests have reportedly been made.

Since Russia started its invasion of Ukraine 12 days ago, Russia official have detained at least 13,000 protesters in 147 cities, according to The Washington Post. 

Spontaneous, mass demonstrations in Russia are illegal.
