Meanwhile in another North Caucasus republic of Ingushetia, two servicemen were slightly injured in a gunfire attack on a traffic control checkpoint late Thursday.
"Shots were fired with shoulder-held grenade launchers and automatic rifles at the Volga-16 checkpoint outside the village of Yandare," said a source from the republic's law enforcement services.
Russia's volatile North Caucasus republics, particularly Chechnya, Dagestan and Ingushetia, have been plagued by violence stemming from militants and criminal gangs. The government is struggling to contain the insurgency.
