At least five militants have been killed during a police sweep in Russia's North Caucasus republic of Dagestan, a police spokesperson said on Wednesday.
The spokesperson said four police officers were injured during the operation in a village in Dagestan's Khasavyurt region.
Earlier on Wednesday, unidentified assailants killed one police officer and injured another in an attack in Dagestan's city of Derbent.
Sporadic terrorist attacks and militant clashes are common in Russia's mainly Muslim North Caucasus republics, especially Chechnya, Dagestan and Ingushetia.
Russia has been fighting militants in the North Caucasus since the mid 1990s, including two separatist wars in Chechnya.
