Officials are investigating the deaths of 15 elephants over the past month in Kenya’s Amboseli national park. The Kenya Wildlife Service (KWS) said 10 of the elephants showed signs of partial paralysis before dying within two days. The remaining five carcasses were too decomposed or had been scavenged, making it impossible to establish the cause of death, the wildlife authority said. The deaths happened in the Kimana sanctuary and Kuku ranch areas surrounding the park, officials said. Kenya has previously recorded incidents of elephants being poisoned as a result of poaching and human-wildlife conflict.
