At least three people have suffered injuries after a bomb explosion ripped through a market in the Russian Caucasus region of Ingushetia.
A law enforcement source, speaking on condition of anonymity, said an improvised explosive device went off near an outdoor market near Nazran -- situated around 1,500 kilometers (930 miles) south of the national capital Moscow -- on Monday, RIA Novosti news agency reported.
The source added that three people were injured in the blast.
Security forces cordoned off the area after the incident, and launched an investigation.
Russia has been fighting militants since the mid 1990s in its North Caucasus region, where the republics of Chechnya, Dagestan, and Ingushetia have been the scene of sporadic attacks and militant clashes.
Violence first broke out in Chechnya in 1994, when 250,000 people were forced to flee to neighboring territories because of a war between Chechen separatists and the Russian army.
After a short-lived period of relative peace from 1996 to 1999, war resumed following attacks blamed on Chechen militant groups.
An estimated 100,000 people have been killed and thousands more displaced in the conflict.
