Policemen uncovered two caches of weapons in the capital of the Russia's volatile North Caucasus republic of Makhachkala, a source from the republic's law enforcement agencies said.

On Sunday evening a 200-liter plastic barrel containing some 9,000 cartridges, 20 grenades, 5 TNT blocks as well as other weapons and 6 car license plates was found at the depth of one meter under a search in a garage, the source said.

The second hideout was uncovered in time of a search in uncompleted construction. The cache contained some 5,000 cartridges and several grenade launchers.

Russia's North Caucasus republics, in particular Chechnya, Dagestan and Ingushetia, have seen frequent attacks on police and officials despite the end of a decade-long special regime for counterterrorism operations in Chechnya last year.
