Assailants fired grenades at a military commandant's office in the Chechen capital Grozny (search) on Monday, wounding eight employees, the Emergency Situations Ministry said.

Two of those injured in the grenade attack in Grozny's Leninsky district were women, said Sergei Kozhemyaka, a duty officer at the ministry's southern branch office. All eight were hospitalized.

Meanwhile, Russian Interior Ministry troops killed one militant and captured two others who had holed up in a house in the restive southern region of Dagestan on Monday, said Khabib Magomedov of the ministry's press service. Two other militants who skirmished with the troops in the village of Nuradilovo in the Khasavyurt region, close to the Chechen border, got away, and two servicemen were wounded.

Khabib said the dead militant was an Arab.

Russia's (search) southern provinces have been plagued by violence, some of it spilling over from war-shattered Chechnya (search). In recent weeks, special military operations increasingly have targeted alleged extremists outside Chechnya.
