One suspected militant has been killed and four police officers have been wounded in a shoot-out in Russia's North Caucasus republic of Daghestan.
Russia's Investigative Committee said the incident took place on June 27 near the village of Khutrakh in Daghestan's western Tsunta district.
Special operations officers located two suspected terrorists in a house near the village and asked them to leave the house to be identified.
The committee said one of the militants threw grenades at the security officers, injuring four of them.
Security officers opened fire and killed one of the suspects.
The special operation is still under way, with another alleged militant reportedly firing from the house.
Daghestan, along with Russia's other volatile North Caucasus republics, continues to experience violence linked to Islamic extremists and organized criminal groups.
