Hundreds of people have been arrested in a crackdown in Russia after thousands gathered for massive anti-corruption protests Sunday in the nation's capital, and other demonstrations were held in dozens of cities across the country.
Huge crowds in Moscow's Pushkin Square protested Saturday against the Russian government, according to The Associated Press, which described the demonstration as among the biggest shows of public opposition to the Kremlin in years. Police estimated the Moscow crowd at about 7,000.
About 500 people were arrested in Moscow, according to Interfax, a privately-held, independent Russian news agency. Russian human rights group OVD-info reported that more than 700 people were detained in Moscow, 34 in St. Petersburg, and between 80 and 100 in other cities.
Independent radio station Ekho Moskvy estimated that unsanctioned rallies in 82 cities and towns assembled 60,000 opposition supporters, in what may be the biggest anti-Kremlin protest since 2008.
Protesters posted photos on social media, some of them selfies, showing people getting taken away by police. Some included playful or self-deprecating remarks.
Alec Luhn, a reporter for The Guardian, a British-based media outlet, wrote on Twitter that despite his showing press credentials to police, he was arrested at the rally and charged with "administrative violation for participating in unsanctioned rally."
He later tweeted that he'd been released after more than five hours.
Alexei Navalny, who is a leader of the anti-corruption movement against President Vladimir Putin, was arrested while walking from a nearby subway station to the demonstration, the AP said.
Navalny's spokesperson, Kira Yarmysh, told Interfax the opposition leader had been placed under arrest until Monday, when a hearing is to be held.
The deputy director of Navalny's organization, the Fund for Combatting Corruption (FBK), which had called for the protests, said the organization's offices had also been raided by police.
The FBK conducts investigations into senior Russian officials and releases its findings in slick, irreverent videos. The protest today was organized to demand that Russian authorities look into the fund's latest investigation, released this month, which alleged that Russian prime minister and ex-president Dmitry Medvdev had amassed a massive property empire using a corrupt scheme based on phones charities.
The investigation alleged Medvedev had built himself vast mansions, bought vineyards and yachts worth as much as a $1 billion. The video laying out the investigation has been watched by at least 9 million people. Authorities have ignored the claims and refused to investigate.
The allegations around Medvedev appear to have struck a chord in Russia, as pressure on freedom of expression has reached a peak at the same time people's living standards have fallen.
The State Department criticized the arrests, and called on Russia to immediately release all the demonstrators who had been detained.
"The United States strongly condemns the detention of hundreds of peaceful protesters throughout Russia on Sunday," acting spokesman Mark Toner said. "Detaining peaceful protesters, human rights observers, and journalists is an affront to core democratic values. We were troubled to hear of the arrest of opposition figure Alexei Navalny upon arrival at the demonstration, as well as the police raids on the anti-corruption organization he heads."
The demonstrations in Russia followed protests in neighboring Belaruson Saturday against that country's president, Alexander Lukashenko, who has ruled the small, landlocked country since 1994.
The Belarus demonstrations resulted in roughly 400 arrests, a human rights group told the AP.
