Four people, including one Malian national, have been arrested in Zimbabwe after 173kg (27 stone) of ivory was seized at Harare International Airport over the weekend.
The haul was valued at $43,250 (£28,187) and was destined for Singapore.
Caroline Washaya-Moyo, from the Zimbabwe Parks and Wildlife Management Authority, said such smuggling was a big problem for the wildlife officials.
