Questions are being raised in Fiji over a large shipment for the military from Russia, believed to be guns and ammunition.

Twenty containers arrived at Suva's Kings Wharf yesterday and according to local media they were escorted under heavy security to the Queen Elizabeth Barracks.

The opposition spokesperson for foreign affairs, Ratu Isoa Tikoca, says the containers are filled with arms, two trucks and a helicopter.

He says it's highly irregular as it didn't go through Parliament for approval.

Acting police commissioner brigadier, General Sitiveni Qiliho, told the Fiji Times the police were involved in the planning of the shipment.

The consignment follows another last month from South Korea.
