The Kilimanjaro Safaris attraction at Disney's Animal Kingdom reopened on time this morning for normal operation after a truck engine fire closed the ride Sunday afternoon.

The fire was caused by a damaged engine hose. The visitors riding in the vehicle were evacuated and one 8-year-old girl reportedly injured a knee while she was exiting the vehicle and was taken to Celebration Health for treatment, a Walt Disney World spokeswoman said. Three others were treated at the scene for minor injuries.

Kilimanjaro Safaris involves rides aboard a multi-passenger truck, through various recreated African habitats showing off captive animals such as elephants, giraffes and lions. The ride follows a storyline that has riders on the truck pretend they are looking for poachers in an African wildlife preserve.

On Sunday the truck fire caused the truck to break down in an area that did not have any animals, said spokeswoman Andrea Finger.

The truck's engine hose was replaced and the truck is fully operational again, she said.
