Four militants died on Sunday in Russia's North Caucasus Republic of Dagestan after a gun battle with local security forces, an Investigative Committee source said.
"The incident took place in Khasavyurt on the Aksayevsky Highway," the source said. "Security forces tried to stop a vehicle for a check, but people inside opened fire. In the course of the gunfight, four people in the car were killed. The security personnel were unhurt. The identity of those killed is being established."
Dagestan and its neighboring republics are often the scene of armed clashes between Islamic militant groups and the security forces.
