Chester Zoo staff are still working to account for all animals affected by huge fire at the Monsoon Forest habitat.
Fire Crews were called to the zoo at 11.28am and there are currently 15 fire appliances in attendance at the scene.
Crews – wearing breathing apparatus and using main jets - are currently tackling the blaze in a building on the site, which is 100m by 25m.
The zoo has been evacuated and there are no reports of any injuries at this time.
The zoo’s teams are now assessing the situation. Critically endangered Sumatran orangutans and other mammals are all accounted for. We are working hard to account for all other species.
Drivers are advised to avoid the area whilst emergency services continue to work at the scene.
The zoo’s The Lanterns event this evening has been cancelled and ticket holders notified by email. The zoo remains closed.
Fire investigators say the fire at Chester Zoo at the weekend was caused by an electrical fault.
Chester Zoo has thanked all those who have donated after a fire killed a number of animals - vowing to continue its conservation mission.
