Story highlights EU foreign policy chief says case adds to "upsurge in politically motivated intimidation"

The three women were sentenced to two years' imprisonment for hooliganism

Arrests were made outside court as the verdict was delivered, state media reported

Three members of Russian female punk rock band Pussy Riot were sentenced to two years in prison Friday after they were found guilty of hooliganism for performing a song critical of President Vladimir Putin in a church.

The five months they have spent in detention since their arrests in March count toward the sentence, Judge Marina Sirovaya said.

The judge said the charges against the three young women -- Nadezhda Tolokonnikova, Maria Alyokhina and Yekaterina Samutsevich -- had been proved by witnesses and the facts.

The Pussy Riot members were charged after screaming, "Mother Mary, please drive Putin away," in a protest act in February inside Christ Savior Cathedral, one of Moscow's grandest houses of worship.

Sirovaya rejected the women's defense that they were acting from political motives, ruling that they had intended to insult the Russian Orthodox Church and undermine public order.

However, the fact that two of them have young children was a mitigating factor in the sentencing, the judge said.

The defendants were accused of offending the churchgoers present -- through their actions, obscene language and their clothing -- and showing a lack of respect for the rules of the Orthodox Church. They ignored requests to stop their brief unscheduled protest performance, the court heard.

While their actions outraged many of Russia's faithful, their high-profile trial prompted international concern about freedom of speech in Russia.

The U.S. Embassy in Moscow said on its official Twitter feed that the sentence was "disproportionate."

European Union foreign policy chief Catherine Ashton condemned the court's decision as "deeply troubling."

"Together with the reports of the band members' mistreatment during their pre-trial detention and the reported irregularities of the trial, it puts a serious question mark over Russia's respect for international obligations of fair, transparent, and independent legal process," she said.

"It also runs counter to Russia's international obligations as regards respect for freedom of expression."

Urging Russia to reverse the sentence, Ashton said the 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."

Rights group Amnesty International said that the court's decision was "a bitter blow for freedom of expression in the country" and that the women were now "prisoners of conscience."

Amnesty believes that the women's conduct "was politically motivated, and that they were wrongfully prosecuted for what was a legitimate -- if potentially offensive -- protest action," it said in a statement.

John Dalhuisen, director of Amnesty International's Europe and Central Asia Program, urged Russian authorities to overturn the sentence and release the trio unconditionally.

He also highlighted recent measures "restricting the freedom of expression and association" introduced after a wave of popular protests that accompanied elections earlier this year. "This trial is another example of the Kremlin's attempts to discourage and delegitimize dissent. It is likely to backfire," he said.

Human Rights Watch also said the women should never have been prosecuted for a hate crime.

"The charges and verdict against the Pussy Riot band members distort both the facts and the law," Hugh Williamson, the rights group's Europe and Central Asia director, said in a statement.

Earlier, a number of arrests were made outside the court, where protesters gathered as the verdict was read, RIA Novosti reported.

The women are expected to appeal the court's decision.

The charge of hooliganism aimed at inciting religious hatred carried a potential sentence of up to seven years in prison.

None of the three women is older than 30. They have been in custody since their arrest shortly after the unexpected performance.

They looked calm and occasionally smiled and exchanged remarks as they stood, sometimes in handcuffs, behind a glass wall in the court, listening to the lengthy ruling.

Moscow district court heard that the three worked together to carry out their "criminal act which violated public order" -- in an action that "went against tradition and is a great insult to the church and people."

The three wore revealing, brightly colored clothing and covered their faces with balaclava-style masks in a style "inappropriate" for a church before making use of a microphone and electric guitar, the court was told.

Video footage of the "punk prayer" protest song was placed online, although the judge said it was not clear who had posted it.

Sirovaya said that the apologies by the defendants "were not sincere" and described their conduct as "an unprecedented act of hooliganism by women."

Evidence from character witnesses for the three women was also read out. Alyokhina was described as being a writer of poetry, a vegan and a good mother, RIA Novosti said.

Pop star Madonna last week performed Pussy Riot-style in a face mask and with the group's name on her back during a packed Moscow gig. She's one of a number of celebrities to back the women's cause.

"Everyone has the right to free speech, everywhere in the world. Maria, Katya, Nadia, I pray for you," Madonna said at Tuesday's concert, according to RIA Novosti. "They did something brave with their action. And I am praying for their freedom."

Rallies in support of Pussy Riot were also organized Friday outside Russian embassies around the world, including in London and Washington.

Putin criticized the women's action this month but said they should not be judged "too harshly," RIA Novosti said. He added that he hoped the court makes "the right decision."

Pussy Riot specializes in sudden, often illegal public performances, including one in Moscow's Red Square.

The "punk prayer" was inspired by the women's anger about the relationship between the Russian government and the Orthodox Church, according to the band's manager, who is married to one of the women.

The Orthodox leader Patriarch Kyril has been widely reported as saying Putin's years in power have been a miracle from God.

Putin won reelection to the presidency in March in a vote that international observers said did not meet international standards.

The presidential election came just months after allegations of fraud in parliamentary elections prompted the largest anti-government demonstrations Russia had seen in two decades.
