The three women, Nadezhda Tolokonnikova, 22, Maria Alyokhina, 24, and Yekaterina Samutsevich, 30, were convicted on Friday (17 August) of hooliganism motivated by religious hatred for performing a "punk prayer" in Moscow's Christ the Savior Cathedral in which they called on the Virgin Mary to rid Russia of President Vladimir Putin.
In Bulgaria, the monument to the Soviet Army awoke on Friday with a new look, with heads of Russian soldiers’ sculptures hooded with coloured balaclavas, a trademark for the punk group. In Brussels, some 100 demonstrators gathered in front of the Russian Mission to the EU, but were moved by the police next to the neighbouring US Embassy.
Catherine Ashton, the European Union's foreign policy chief, said the two-year sentences give to the women were "disproportionate" to the crime and added to the intimidation of opposition activists in Russia.
"Together with the reports of the band members' mistreatment during pre-trial detention and the reported irregularities of the trial, it [the verdict] puts a serious question mark over Russia's respect for international obligations of fair, transparent and independent legal process," Ashton said.
"This case adds to the recent upsurge in politically motivated intimidation and prosecution of opposition activists in the Russian Federation, a trend that is of growing concern to the European Union," she said in a statement.
Home Affairs Commissioner Cecilia Malmström tweeted: “Very sad to hear the sentence against Pussy Riot. Totally unproportionate!”
In Washington, White House spokesman Josh Earnest said in a statement, quoted by Reuters: "While we understand the group's behaviour was offensive to some, we have serious concerns about the way that these young women have been treated by the Russian judicial system."
The Pussy Riot case, seen as a test of the extent of Putin's tolerance of dissent, has added to the strain already placed on relations between Moscow and European governments by their opposed positions on the crisis in Syria.
Pussy Riot has been publicly backed by dozens of prominent musicians, including Paul McCartney, Madonna, the Red Hot Chili Peppers, Björk, Bryan Adams, Sting, Yoko Ono and many others.
Adams tweeted: "Outrageous ... Russian singers jailed just for speaking their mind?"
On his Twitter account, "Lord of the Rings" actor Elijah Wood posted "a shame to hear the Pussy Riot were found guilty, but not surprised."
But in Russia itself, the society appears divided with regard to the sentencing. Hundreds of intellectuals protested the verdict, with former chess world champion Gary Kasparov was detained and reportedly beaten for participating in the protest outside the court.
But a large proportion of the Russians see the sentences as a fair punishment for desecrating a holy place and for undermining Russian cultural values.
