Two people have died in a series of bomb attacks in Ingushetia where Russian security forces are facing a growing Islamist insurgency.
At least 33 others were injured in the blasts including several senior police officers according to the region’s interior ministry.
Officials say a police patrol went to a house in the regional capital Nazran to check reports of an improvised explosive device.
The bomb exploded killing a police officer and the house owner. Two more devices then went off as police support units arrived on the scene.
The chief of police in Nazran and the head of the city’s investigation unit are said to be among the wounded.
The booby-trap bomb attacks mark an upsurge of violence in Ingushetia, Chechnya and neighbouring Dagestan nearly a decade after Russian security forces crushed Chechen rebels in the second of two separatist wars.
