A police officer has been killed by suspected militants in Russia's restive Republic of Daghestan in the North Caucasus.
Local law-enforcement officials say that unknown armed attackers opened fire from a vehicle at the police officer's car in Daghestan's western city of Khasavyurt on July 9.
The officer and a passenger in his car were seriously wounded in the attack. The officer -- whose name was not released -- died later in the hospital.
On July 7, another police officer was killed and three officers were injured in a counterterrorist operation launched on July 6 in Daghestan's central Untsukul district.
Officials say seven suspected militants have been killed so far.
