A four-year-old girl has been killed after slipping off the edge of the Grand Canyon and falling several hundred feet. The girl's father immediately scrambled down the cliffs and started trying to revive her. National Park Service spokeswoman Maureen Oltrogge said he started cardiopulmonary resuscitation with the help of a park ranger who abseiled into the canyon. The child's body was 400 to 500ft below the rim, Ms Oltrogge said. The area where she fell is a combination of sheer drops of 30 to 50ft, before slopes lead to more drop-offs. The girl is said to be from Arizona, but her name and hometown were not immediately released by authorities. The canyon, in Arizona, is one of America's leading tourist attractions.
