Russian security forces rounded up more than 1,000 demonstrators on Wednesday as thousands of people in cities across the country rallied in support of jailed opposition leader Alexey Navalny, according to OVD-Info, an independent monitoring group.

The unauthorized marches fell short of the 500,000 protesters that Navalny’s team had aimed to draw, but big crowds in Moscow, St. Petersburg and other cities has shown the dedication of his supporters, who are demanding that the hunger-striking Kremlin critic be released and allowed to receive independent medical care.

He said that “unfriendly actions against Russia do not stop” and claimed it has become “customary to pick on Russia on any possible occasion,” despite it being “a welcoming country, open for real friendship.”

“We behave with the utmost restraint and modesty, often do not respond at all not only to unfriendly actions, but even to outright rudeness. We want to have good relations with everyone, but we see what is happening,” Putin said.

“We really don’t want to burn bridges. But if someone perceives our intentions as indifference or weakness and is ready to burn or even blow up bridges, then Russia’s response will be asymmetrical, swift and harsh.”

His words come at a time of heightened tensions between Russia and Western powers. The US last week imposed sweeping sanctions against Russia for its interference in the 2020 US election, its
