"Thirteen men were arrested, and a lot of explosives and weapons were seized," said Konstantin Krivorotov, a senior investigator at the Russian Prosecutor General's Office's department for the Southern Federal District.
Krivorotov said some of the weapons had been seized by gunmen in Ingushetia, a Russian republic neighboring Chechnya, during the June 22, 2004 attack on government buildings, while the rest had been brought from Chechnya in 1996.
Law enforcement bodies also found an arms cache of international terrorist Abu Dzeit who had a part in the three-day school siege in Beslan last year and who was killed in Ingushetia in February.
A total of more than 20 kilograms of explosives, 24 assault rifles, 30 pistols, five machine guns, a lot of grenades, grenade launchers, cartridges, and a few self-made bombs were found in caches in Chechnya, Kabardino-Balkaria, and Ingushetia.
