NAZRAN, Russia (Reuters) -- Attackers fired grenades today at the police headquarters in the Russian province of Ingushetia, which borders Chechnya, killing one officer, officials said.
Two other police were injured in the attack on the Interior Ministry building in Nazran, Ingushetia's main city, a ministry official said.
An upsurge in attacks in the heavily Muslim North Caucasus over the past year has troubled the Kremlin, a decade after government forces drove separatists from power in Chechnya.
Ingushetia, which lies west of Chechnya, has been plagued by nearly daily attacks targeting law enforcement and government officials.
The assailants in today's attack fired about five grenades, apparently aiming for an auditorium in the police building, before fleeing in a car, the official said.
