Hundreds have been arrested across many cities in Russia. People are protesting what many say is forceful mobilization to join the Ukraine war.
Authorities are seeking to crack down on dissent over the war.
Girls as young as 14 years old were among those detained in St Petersburg, reports say, with authorities using stun guns and batons.
In Moscow, screams were heard after a woman was put into an empty prisoner transport van, according to a human rights organisation.
More than 700 people have been arrested in this weekend’s protests, according to human rights organisation OVD-Info.
