The Russian Interior Ministry says four servicemen have been killed and seven wounded by rebels in a restive region in Russia's North Caucasus.
Madina Khadziyeva, a spokeswoman for the ministry's branch in the province of Ingushetia, said that militants ambushed an Interior Ministry convoy Monday in the region's mountain forests close to the administrative border with Chechnya. She said the attack occurred near the village of Dattykh, but gave no further details.
An Islamic insurgency spread across North Caucasus after two separatists wars in Chechnya. While Chechnya itself has become more stable in recent years under the steely grip of a Moscow-backed strongman, neighboring provinces have seen an increase in attacks on police and other authorities.
Ingushetia recently had been less volatile than some of the neighboring regions, so the casualty toll in Monday's attack was unusually high.
