The significant part of the arms used by the North Caucasus militants is supplied from military depots, Russia's Deputy Prosecutor General Ivan Sydoruk said on Monday.
"The situation is worsening due to the vast corruption on the territory of the [North Caucasus Federal] district, where bribery has been forming for decades," Sydoruk said.
He said all of the recent attempts to kill law enforcers were made using state-of-the-art arms and explosive devices.
Over the nine months of 2010, 205 police officers were killed and 489 injured in the North Caucasus.
"Dagestan, Chechnya and Ingushetia are the most volatile regions in terms of militant attacks on police officers as well as Kabardino-Balkaria, where law enforcers are targeted in order to destabilize the situation and demonstrate the power of the militants," the Sydoruk said.
The deputy chief prosecutor said the main cause of the North Caucasus problems is the overall unemployment and low living standards. The district sees about 449,000 people unemployed with over 40 percent of the entire population living below the poverty level.
