Russian opposition figure Alexei Navalny was sentenced to 2.8 years in a penal colony Tuesday following a trial that his supporters have criticized as politically motivated.
Thousands of Russians took to the streets in Moscow and St. Petersburg over the verdict and over 1,400 people were detained.
Video footage shows instances of mass riot police brutality, as police beat both citizens and journalists on the street with truncheons.
Western leaders have condemned Navalny's jailing as well as the extreme tactics used by police to suppress the protests.
