Eleven police officers were injured in a grenade attack on a police station in Russia's North Caucasus republic of Ingushetia, investigators said on Tuesday.
An unknown assailant attacked a police station on the Kavkaz federal highway near Nazran, the largest city in the republic, using a grenade launcher late on Monday. No one was reported killed.
"As a result of the attack, 11 police officers sought medical assistance," investigators said. Earlier reports said seven officers had been injured.
Ingushetia has seen an upsurge of militant violence lately, with frequent attacks on police and officials.
The Kremlin has pledged to wage "a ruthless fight" against militant groups, but also acknowledged a need to tackle unemployment, organized crime, clan rivalry and corruption as causes of the ongoing violence in the North Caucasus region.
