Abkhazia is the focus of an ongoing feud between Russia and Georgia, which accused the Kremlin of planning to annex the area through "armed aggression" when Russia deployed an additional 1,000 peacekeepers in the area in April.
Shota Utiashvili, chief analyst at the ministry, told RIA Novosti that the peacekeepers were arrested "transporting 35 crates of munitions. The crates contained guided missiles."
He said they were arrested "over a discrepancy between the documentation on the cargo, and the actual cargo."
Mamuka Kurashvili, the commander of the Georgian peacekeeping battalion in the Georgia-South Ossetia conflict area, told reporters that no ammunition cargo had been authorized by Georgia, and that the munitions cargo was being accompanied by airborne troopers.
RIA Novosti has not yet received confirmation of the arrests from the Russian peacekeepers stationed in the area.
