Large silverback gorilla tries to attack zoo visitor through glass

A scary video has emerged from the US of a large silverback gorilla trying to attack a zoo visitor through the glass of his enclosure.

The footage, filmed at Henry Doorly Zoo in Omaha, Nebraska last week, show Kijito the silverback charging and jumping into the glass when the visitor has his back turned to the enclosure.

According to the filmer, the very same gorilla broke a window at the zoo last year.

"He is quite the character and plays with us whenever we go to the zoo," she wrote online.
