An Azeri national was put onto an international wanted list Sunday over the killing of a football fan, a day after 100 people were detained near the Kremlin while planning to hold a nationalist rally over the death.
Andrei Uryupin, an 18-year-old CSKA football fan, was stabbed to death during a fight in the Moscow region town of Podolsk on Saturday, while a 19-year-old friend was injured. The attacker, who fled, was identified as Nail Khosruvlu, 20.
The incident echoed several recent brawls that have escalated ethnic tensions.
Police spokesman Anatoly Lastovetsky said some of those detained Saturday on Manezh Square were carrying weapons, including guns that fire rubber bullets.
A heavy contingent of police officers was deployed in and around the sprawling square after calls appeared on the Internet for an unauthorized gathering to mark Uryupin's death.
In December, about 5,000 people chanting "Russia for Russians" gathered on Manezh Square and beat dark-skinned passers-by in what was also a reaction to the killing of a football fan during a fight with Caucasus natives.
Meanwhile, City Hall has banned an annual march of 15,000 nationalists on Nov. 4, the People's Unity Day holiday, over a misprint in the petition submitted by organizers, nationalist leader Dmitry Dyomushkin told Interfax on Friday.
March organizers will file another petition to hold the march and will also appeal the denial in court.
The marches have been held since 2005, when Russia started celebrating People's Unity Day, which marks Russia's victory over Polish invaders in 1612.
