A Chinese tour guide stabbed and killed a tourist who was visiting Kenya's famed Maasai Mara Game Reserve after an argument over the seating arrangement for dinner, police and a lodge manager said on Tuesday. John Kiruti, manager of Keekorok Lodge, which is within the park, said the woman, also a Chinese citizen, sustained serious chest injuries in the incident late on Monday and died as she was being transferred to another tourist camp for treatment. “The tour guide who had brought three clients from his country for two nights differed with the couple … over the sitting arrangement at dinner time,” Kiruti said.
