One of the world's oldest silverback male gorillas has died at Longleat Safari Park in Wiltshire.

Nico, 56, died in his sleep on 7 January and staff at the park say they are "truly saddened".

A spokesman said: "It is with deep regret and huge sadness that we have to announce the death of Nico, our much-loved western lowland gorilla.

"His main keeper has been working with Nico... since 1989 and has forged an extraordinarily close bond with him."
