A group of protestors gathered this afternoon outside the Russian ambassador’s Washington residence to protest the jailing of the three Russian punk rock musicians from the group Pussy Riot. The musicians—Maria Alyokhina, 24, Nadezhda Tolokonnikova, 22, and Yekaterina Samutsevich, 29—were sentenced to two years in prison today for “hooliganism motivated by religious hatred,” the BBC reported.

“We’re opposing Putin’s oppression of free expression,” one protestor said, standing on the sidewalk outside of the Russian mansion.
