The square in the city centre was surrounded with police vans and policemen were leading people away into the vans, an AFP correspondent at the scene said, counting over 100 detained at the unauthorised demonstration.
"Our brothers are being detained! Why are Muslims always to blame, why are they detaining us?" one protester shouted.
"Why can't we express ourselves," complained another protester, Makhmud, 45. "We are worried about what is happening with our brothers in Myanmar."
The plight of the Rohingya minority in Myanmar, where nearly 300,000 have fled their homes from what they say are state-orchestrated mass killings into neighbouring Bangladesh, has seen Russia's Muslims stage several protests, particularly after a call by Chechen strongman Ramzan Kadyrov.
Moscow however has been mute over Myanmar. "We're against any sort of violence," Putin said Tuesday when asked about Kadyrov's position, adding that "any person has a right to his opinion regardless of his post."
Russia and Myanmar are also allies who signed a military cooperation agreement last year, with Moscow of having exported military aircraft and artillery to the country.
