Russia's Federal Security Service must identify who plans race-related public disturbances or disseminates ethnic and religious hatred, President Dmitry Medvedev said on Friday.
The Russian capital saw its biggest public disturbances for almost a decade when nationalists and football hooligans clashed with police on Saturday.
"To identify the organizers of this kind of provocations is also one of the tasks of the Federal Security Service," Medvedev said. "Our response to any manifestations of ethnic intolerance, the implementation of unrest, and inciting ethnic and religious hatred will be absolutely unambiguous."
The fans were protesting the death of Yegor Sviridov, 28, who was killed in a brawl with migrants from Russia's North Caucasus region.
They were angered by the release of five of the six suspects in the killing, accusing the police of being unable to bring those responsible to justice. Following Saturday's riots, Moscow police chief Vladimir Kolokoltsev promised to detain the released suspects. At least four have been re-arrested.
On Thursday, Medvedev blamed investigators who released suspects in the death of the football fan in Moscow for the race-hate riots.
He called on Russia's police and prosecutors to take measures to punish all those responsible for the crime.
