Security forces in Russia's southern republic of Dagestan say they have killed six militants in two days of clashes in a mountainous area.
Four militants died when police and special forces stormed a house in the village of Gelim-Batan late on Wednesday, officials said.
Earlier, two militants died in separate clashes with security forces.
Dagestan, bordering Chechnya, has long been plagued by violence - often linked to the Chechen rebel movement.
Russia blames Islamist militants and criminal gangs for the unrest in the region.
