Russian authorities have arrested over 13,000 anti-war protesters as its crackdown on dissidents within the country continues.
People across the country are protesting Russian President Vladimir Putin's decision to invade Ukraine, beginning a war that has killed at least 331, according to the United Nations.
OVD-Info, an independent human rights project focused on political persecution in Russia, published the figure on Sunday.
The arrests come after Putin has increased attempts to stifle any opposition to the government's invasion of Ukraine, also blocking several major social media outlets within the country, such as Facebook and Twitter.

One human rights activist, Marina Litvinovich, called for mass protests last week in a Facebook video, stating that the Russian people oppose the war.
"We, the Russian people, are against the war Putin has unleashed. We don’t support this war, it is being waged not on our behalf," Litvinovich said. "I know that right now many of you feel desperation, helplessness, shame over Vladimir Putin’s attack on the friendly nation of Ukraine. But I urge you not to despair."
She was arrested shortly after uploading the video to Facebook.

"I want to ask Ukrainians for forgiveness. We didn’t vote for those who unleashed the war," she said.
Putin also signed a law on Friday which aims to punish journalists with prison time for publishing news that contradicts the government's statements about Russia's war in Ukraine.
People who violate the law will face up to 15 years in prison.
The protests aren't limited to the streets either, with some people signing open letters expressing their opposition to Russia's invasion of Ukraine.

One Museum in Moscow, Garage, said that it would be halting and postponing work on exhibitions "until the human and political tragedy that is unfolding in Ukraine has ceased."
"We cannot support the illusion of normality when such events are taking place," the statement by the museum read. "We see ourselves as part of a wider world that is not divided by war."
