Ten lions have been found dead in Tanzania's Ngorongoro Conservation Area, with preliminary findings suggesting they may have been poisoned. The deaths have raised concerns about the protection of lions in one of Africa's best-known wildlife ecosystems.

The lions were discovered on September 18 in the Ndutu area of Endulen Ward in the Arusha region, according to the Ngorongoro Conservation Area Authority. The authority said it had opened an investigation to determine how the animals died and identify those responsible.

The preliminary findings indicate that the lions may have died after ingesting poison. The cause has not been confirmed, and authorities are continuing their investigation.

Poisoning has been a recurring threat to large carnivores in parts of East Africa. Such incidents can be linked to conflicts between predators and livestock owners, although the authority has not established a motive or identified anyone responsible in this case.

The Ngorongoro Conservation Area is a UNESCO World Heritage Site and an important tourism destination in northern Tanzania. It contains a wide range of wildlife, including lions, elephants, buffaloes and endangered black rhinos.

The deaths come as wildlife authorities in the region face continuing concerns about threats to protected animals. In neighboring Kenya, police last month arrested four people while investigating the deaths of 18 elephants in the Amboseli area.

The investigation in Tanzania is expected to establish the circumstances surrounding the lion deaths. Until those findings are available, authorities have not confirmed that poisoning was the definitive cause
