Russia's National Antiterrorism Committee (NAK) said a security operation in the North Caucasus republic of Daghestan resulted in one militant being killed and large amount of explosive material being seized.
NAK said security forces conducted an operation in the Kyzylyurt district of Daghestan on October 6 and killed Alidibir Asudinov, described as a bomb maker for a local militant group.
A search of a home belonging to the militant group turned up some 170 kilograms of explosive material and a vehicle that was being rigged with enough explosive material to cause a powerful blast.
NAK said the group planned to carry out a series of terrorist attacks in Daghestan.
The operation was conducted one day after a bomber in nearby Chechnya killed five policemen outside a concert hall in the Chechen capital Grozny.
