Thirteen monkeys have been killed in a fire at Woburn Safari Park in Bedfordshire in England.
The blaze broke out in the early hours of the morning in the Patas monkey house within the African Forest drive-through enclosure of the park.
A spokesman for the park said: "Staff and fire crews attended the scene; however, devastatingly for everyone at the park, none of the 13 animals could be saved."
All other animals within the jungle drive-through enclosure are being monitored, but early signs suggest they have not been affected.
An investigation is under way into the cause of the fire and the park will remain open.
Bedfordshire Fire and Rescue Service said the blaze was spotted by security guards on a routine patrol before firefighters arrived at 2.37am.
"They found the outbuilding housing Patas monkeys was well alight and its roof had fallen in," it said in a statement.
"They fought the fire using fire hoses while wearing breathing apparatus to protect themselves from the smoke and fumes.
"The building was 90% damaged by the fire."
