A 14 -year -old girl was killed by a lion on the outskirts of Nairobi, Kenya Wildlife Service (KWS) said.
The child was torn off in a residential complex in a ranch next to Nairobi National Park, according to the Conservation Agency.
The alarm was raised by another teenager and KWS Rangers followed tracks to the Mbagathi river, where they found the remains of primary school.
The lion was not found, but Kws said he had put a trap and deployed research teams to search for the animal.
The agency added that additional security measures had been taken to prevent other attacks.
Nairobi National Park is only 10 km (six miles) from the city center and houses animals such as lions, buffaloes, giraffes, leopards and cheetahs.
It is closed on three sides to prevent animals from browsing the city, but it is open to the south to allow animals to migrate in and outside the region.
Although the lions often conflict with humans in Kenya, especially on cattle, it is not common for people to be killed.
Last year, video surveillance images captured when a lion was snatched a rottweiler dog from another house near the Nairobi National Park.
KWS also reported that a 54 -year -old man was killed by an elephant on Saturday. The incident occurred in the central country of Nyeri, about 130 km (80 miles) north of Nairobi.
The elephant paid in a simple forest when he attacked the man, who suffered serious thoracic injuries, fractured ribs and internal trauma.
He was taken to a neighboring hospital where he died of his injuries.
Paula Kahumbu, leader of the fauna-speaking conservation group, said that deaths were not isolated incidents and urged KWS to improve “risk assessments and guarantee precise and real-time communication of fauna movements and behaviors, especially in high-risk areas such as Savannah Ranch”, where the 14-year-old child was killed.
She also said that all the lodges, camps and residential developments near the areas where fauna lived should be “equipped with disgusting anti-predator systems-including lights, alarms, secure fences and anti-referring spraying”.
“Prevention is our first and the best line of defense,” she added.
