reported that the haul, which involved, 317 pieces, is believed to be the largest in Kenya for several years.
The Kenyan Wildlife Service (KWS) said that they believe the elephants which the ivory came from died naturally.
Two suspects have been arrested in relation to the seizure.
Last year, Kenyan authorities have seized 300kg (660 lbs) of ivory and rhinoceros horns which had been hidden in coffins and was to be shipped to Laos.
Ivory smuggling has been a problem mainly due to demand from wealthy buyers in the US and Asia.
