Police and security forces killed three alleged militants, including a woman, in Russia's volatile North Caucasus republic of Daghestan during a counterterrorism operation.
Daghestani Interior Ministry officials say the operation's "active phase" is over.
The security troops encircled a house in Daghestan's western city of Khasavyurt after someone inside opened fire on police on May 5.
Earlier on May 5, an unknown assailant shot a Khasavyurt police officer who was rushed to hospital with two serious gunshot wounds.
Police said earlier that the shooter may be inside the encircled house.
Daghestan has been plagued by violence linked to Islamic extremism and organized crime for years, with thousands of people being killed and injured.
