Tourists Scream As Lion Leaps At Them With No Fence

Safari park visitors were terrified when a lioness leaped at them with no fence between them.

A visitor's smartphone video shows the lioness sitting alongside a male lion at the Bioparque Estrella in the city of Monterrey, in the north-eastern Mexican state of Nuevo Leon.

Instead of a fence keeping visitors away from the big cats, a deep, wide trench separates them.
