#AceWorldNews says that police said that about 500 people were in Moscow and St Petersburg at unauthorized rallies reportedly in protest at the imprisonment of seven opposition activists.
A spokesman for the Moscow police department said 420 people were detained during a rally in down-town Moscow, which it said had been attended by some 500 people in total.
The event had not been approved by Moscow City Hall and thus violated the law on public gatherings, a police spokesman earlier told RIA Novosti.
Those detained “were continuing their illegal actions despite police demands to stop,” the spokesman said, adding that they face misdemeanor charges.
Sixty people were detained at a similar rally in St. Petersburg, which, according to city police, gathered about 100 activists.
