Two people including a Chinese national were over the weekend killed by hippos in two different incidents in Lake Naivasha.
Kenya Wildlife Service named the tourists, but the Chinese embassy in the country has not released a comment at this stage. His colleague survived with minor bruises and was treated at Naivasha District Hospital.
Hippos are considered the most unsafe land animal in Africa because the world's third largest mammal can be extremely aggressive and territorial.
The Chinese national was pronounced dead on arrival at the Naivasha District Hospital, while another tourist Wu Peng, 62, survived the attack, according to the Kenya Wildlife Service.
David Kilo, chairman of Lake Naivasha Boat Owners Association, told Kenya's Star newspaper that rising water levels had reduced pasture areas for hippos, forcing them on to farms and hotel grounds, and increasing contact between the mammals and humans.
Witness James Omollo said the foreigner got too close to the animal which turned against him, biting him on the chest.
In an earlier incident, an illegal fisherman was attacked by another hippo and died on the spot.
"The man was also bitten on the chest and his injuries were serious and he died minutes after he was retrieved from the lake", he said.
The deaths brought to six the number people who have been killed by hippos around Lake Naivasha so far this year.
Naivasha police boss Samuel Waweru confirmed both incidents and mentioned that the bodies were taken to the mortuary.
