# Four people have been arrested in Kenya as investigators try to establish what killed 18 elephants in the Amboseli ecosystem. The Kenyan Wildlife Service says the animals died between June and last month, with preliminary laboratory tests pointing to possible poisoning. Earlier findings suggested cyanide may have been present in pesticide-contaminated tomatoes eaten by the elephants. Authorities have seized several potentially toxic, unlabelled chemicals for testing. The investigation is continuing, while officials stressed that the arrests do not necessarily establish guilt.
