Several hundred women formed human chains in Moscow and Saint Petersburg Sunday, using Valentine's Day to express support for the wife of jailed opposition leader Alexei Navalny and political prisoners.

Around 300 women gathered on Arbat Street in Moscow's historic city centre holding a long white ribbon in temperatures of minus 13 degrees Celsius (8 degrees Fahrenheit).

The gathering came after authorities last week sentenced Navalny, President Vladimir Putin's most prominent critic, to nearly three years in prison and unleashed a crackdown on his supporters.

Female activists said they wanted to express solidarity with Navalny's wife Yulia and other women who have become victims of the crackdown.

"By forming a chain we want to show that we are for love and against violence," Darya Obraztsova, a 22-year-old student, told AFP in Moscow.

"Very brave and nice young women have gathered here," she said, adding she wanted "freedom and justice" for Russia.

In the second city Saint Petersburg, some 100 women formed a similar chain near a monument to victims of political repression.

Some clutched flowers, while others recited poems by Anna Akhmatova, one of Russia's most beloved poets.

"Only love can win over evil," 25-year-old Valeriya Stepanova told AFP in Saint Petersburg.

The new form of opposition rallies is similar to human chains formed by female activists in neighbouring Belarus.

Navalny was arrested and jailed upon returning to Russia last month following treatment in Germany for a nerve agent poisoning.

His jailing sparked widespread protests across Russia that have seen at least 10,000 people detained.

After the crackdown Navalny's team postponed mass rallies until the spring or summer, but urged supporters to use Valentine's Day to try out new -- and safer -- forms of protest.

Navalny's right-hand man Leonid Volkov has called on Russians to stage courtyard protests on Sunday evening, lighting their phone flashlights for 15 minutes and posting pictures of the gatherings on social media.

Navalny's team released pictures and video of small-scale gatherings that took place in eastern Russia and Siberia earlier Sunday, with Russians lighting flashlights, sparklers and small lanterns.

"Love is stronger than fear," said an electronic ticker tape on a residential high-rise in the Siberian city of Tomsk, according to a video released by Navalny's team.

Officials have accused the opposition of acting on orders from NATO and warned that anyone violating the law would be punished.

"We will not play cat and mouse with anyone," Putin's spokesman Dmitry Peskov said.
