Unknown attackers opened fire at a grocery store late on September 17 in the town of Babayurt in Russia's restive North Caucasus republic of Daghestan.
The attackers also left a home-made bomb at the entrance of the store.
Local officials say the bomb was defused and nobody was injured.
Last month, assailants placed mines at a liquor store and threw a grenade at a restaurant in Ingushetia, another North Caucasus republic.
No casualties were reported. Islamic insurgents in the region regularly attack liquor stores and other public places selling alcoholic beverages.
