Police in northern Vietnam have seized nearly 3 tons of ivory smuggled from South Africa in the latest action taken against the illegal trade.

Thanh Hoa provincial police said that the ivory was found in boxes in a truck early on Saturday morning. The account posted on the police website quoted the truck driver as saying he was hired to transport the ivory from southern Dong Nai province to the capital Hanoi.

Police declined to give further information on Monday.

Last year, nearly 7 tons of ivory were seized in Vietnam’s southern commercial hub of Ho Chi Minh city.

Vietnam is one of the world’s major transit points and consumers of ivory and rhino horn. It bans hunting of its own dwindling population of elephants.
