The incident occurred late on Saturday (local time) in the village of Sary-Su during a large wedding celebration attended by most local residents as well as a group of visitors, an official in the district mayor's office told Interfax.
"Nineteen people suffered shrapnel wounds from a grenade blast and one injured woman is in critical condition," the official said.
The RIA Novosti news agency quoted a local police source as saying most of the 19 injured were aged between 17 and 25.
The blast occurred during a brawl between residents of Sary-Su and the visitors, Interfax reported.
"Taking advantage of their superior numbers some youths from Sary-Su beat up the guests," the source said.
"These in turn called some comrades up for help and the conflict reached a new level. In the ensuing brawl one participant threw a grenade."
The source in the mayor's office said police had detained two of the brawl's participants, while village elders had been enlisted to help calm the situation.
