MOSCOW - A bomb exploded outside a mosque in Russia's North Caucasus on Friday, killing two suspected suicide bombers in a region where Moscow is battling an Islamist insurgency.
Russian security forces are trying to quell the unrest in the mostly Muslim region only hundreds of kilometers away from President Vladimir Putin's planned venue for the 2014 Winter Olympics.
The blast occurred at 3.00 a.m. local time at the entrance to a cemetery outside a mosque in the village of Dygulubgey in the Kabardino-Balkaria region, local investigators said in a statement.
Attacks in Kabardino-Balkaria are less common than in the nearby province of Dagestan, but Dygulubgey has been the scene of several insurgent attacks and shootouts with police in recent months.
"At the site of the explosion, the fragments of the bodies of two men have been found," Interfax quoted a regional law enforcement source as saying on the condition of anonymity.
"Nearby was also found a Kalashnikov machine gun which it has been ascertained was among the materials stolen during an attack on traffic police," the source said.
Russia's Investigative Committee said the blast was probably the result of a suicide bombing.
