Thirteen monkeys have burned to death in a safari park north of London after an horrific fire.
It's believed a faulty generator sparked the blaze at Woburn Safari Park, which engulfed the Patas monkey house.
The animals usually lived outdoors in the park's African Jungle enclosure, but they had been brought inside for the winter.

During the blaze the roof caved in, collapsing into the building, officials say. Around 90 percent of the building was damaged and it took a little over two hours to control the fire.
Bedfordshire Fire and Rescue Service's station commander Paul Goddard said nothing could be done to save the Patas monkeys and keepers were liaising with the fire crews.
"[The staff] were obviously understandably shaken and upset with the fatalities to the monkeys," he told local media.
Woburn Safari Park's manager director Drew Mullin said staff were devastated by the deaths and the monkeys had been a popular attraction for visitors.
"Each of the keepers knows these animals. They know the monkeys, they know their names, so for them they have lost something special," he said.
Around 30 other monkeys also lived at the zoo and avoided the blaze.
It comes just two weeks after a fire at London Zoo which killed four meerkats and an aardvark.
