I fell into gorilla enclosure - what happened next was heartbreaking

It was a moment of heart-stopping drama - a five-year-old boy falls into a gorilla enclosure at a zoo and lies unconscious on the ground as a huge silverback approaches.

With his horrified parents watching on helplessly and onlookers shouting for assistance, the silverback stretches out his gigantic arm and everyone holds their breath.

And then to the astonishment of everyone, Jambo the 18 stone gorilla, gently strokes the back of the motionless child then sits to act as a protective guard against the other gorillas.
