A mass brawl broke out in the Moscow region town of Chekhov late Sunday, when local youths attacked Central Asian migrant workers playing football after work.
As a result of the attack, five Central Asian workers were hospitalized, four with gunshot wounds and one with severe injuries caused by a blunt object, a police source told Interfax.
The police source said that law enforcement couldn't explain the attack.
The youths used air guns and other objects close at hand during the fight, the source said, adding that most of the victims are from Tajikistan.
The Federal Security Service is tracing the suspected attackers, a spokesperson for the Interior Ministry said.
