MOSCOW - Foreign Ministers of the European Union are meeting in Brussels Monday to debate the response of the 27-nation bloc to Russia's arrest of opposition leader and Kremlin critic Alexei Navalny and the police crackdown on pro-Navalny demonstrators, as pressure grows to impose sanctions on the Kremlin.

Arriving for the meeting, EU foreign policy chief Josep Borrell said that the most recent "wave of detention is something that worries us a lot, as well as the detention of Mr. Navalny."

EU, US Call on Russia to Immediately Release Navalny, Protesters

EU leaders have called on Russia to immediately release Navalny and all pro-Navalny protesters in detention.

The United States strongly condemned the arrests and use of "harsh tactics against protesters and journalists this weekend in cities throughout Russia," State Department spokesperson Ned Price said in a statement Sunday.

Suppression of Russians' rights to peaceful assembly and freedom of expression, Navalny's arrest, and the crackdown on protests "are troubling indications of further restrictions on civil society and fundamental freedoms," the statement added.

The U.S. is calling on Russian authorities "to release all those detained for exercising their universal rights and for the immediate and unconditional release" of Navalny, Price said, adding that U.S. is urging Russia "to fully cooperate with the international community's investigation into the poisoning" of the Kremlin critic, and "credibly explain the use of a chemical weapon on its soil."

Russia's Foreign Ministry countering that the U.S. efforts to "incite radical elements" on social media would have negative effects on U.S.-Russian relations -- adding American diplomats in Moscow would be summoned for "a serious conversation."

Hundreds of people remained behind bars in Russia Sunday, a day after they were arrested for participating in nationwide street protests demanding the release of Navalny.

Tens of thousands of supporters of jailed opposition politician Alexei Navalny thronged the streets of Russia Saturday, defying warnings from authorities that those attending faced police arrest and additional health risks because of the coronavirus.

The protests were called by Navalny after the opposition leader was jailed upon his return to Russia last weekend from Germany, where he'd been recovering from a poisoning attack that nearly took his life last August.

Independent monitoring group OVD-Info reported about 3,200 arrests as of Saturday night, including Navalny's wife, Yulia, and his aide, politician Lyubov Sobol. Several dozen journalists were also detained.

Yulia Navalnaya confirmed her arrest in Moscow in an Instagram post created from inside a police van, apologizing for the look of her posting. "Sorry for poor quality. Very bad light in a paddy wagon," she wrote Saturday.

Thousands of Navalny's supporters were in the streets of more than 60 Russian cities Saturday to demand the Kremlin critic's immediate release, defying the measures taken by police to break up the protests, which they have declared illegal.

In Moscow, thousands of masked protesters gathered in the city's central Pushkin Square with shouts of "Let him Go!" and "Alexei! Alexei!"

Demonstrators also held signs that read "Freedom for Navalny" and "I'm not Afraid."

"If they arrest me, well OK, I'll miss a day or two of work," said Dmitry, 55, in an interview with VOA.

"I'm here thinking of my children and their futures. Because I absolutely don't like what's happening now in our country these days," he added.

Many of the demonstrators were in their 20s and some even in their teens — a fact government officials have seized on, accusing Navalny of luring minors into harm's way.

"I've known only one president my whole life and I'm tired of him," said Ksenia, 24, in explaining why she'd come.

"I didn't come out for Navalny. I came out for me," said Daria, 17, a high school senior. "I want my country to change."

Crowds also overflowed onto the surrounding side streets and along the city's main Tverskaya thoroughfare.
