Russia police have raided the Moscow office of opposition leader Alexei Navalny as demonstrations calling for a boycott of Russia’s presidential election take place across the country.
A video stream on Sunday morning from Mr Navalny’s headquarters showed police entering the office.
One broadcaster on the stream said police apparently were using a grinder to try to get access to the broadcast studio.
The anchors said police say they had come because of a bomb threat.
Mr Navalny, who has been blocked from running in Russia’s March 18 presidential election, called for nationwide protests on Sunday.
Sizeable gatherings have been reported in the Far East and Siberia, including Vladivostok, and more are set for Moscow and St Petersburg in the afternoon.
