Unconfirmed Russian media reports said police fired shots in the air, while demonstrators threw stones at police.
The reports said 100 protesters were detained. Earlier today, a rights activist said masked armed men dragged him and three TV reporters out of their hotel, beat them, and drove them out of Nazran.
The four had traveled to the city to cover the antigovernment protest.
