A fire at a German zoo killed 26 animals Friday night.
The fire destroyed the petting zoo, which included many wooden buildings that housed Shetland ponies, sheep, goats and a llama, according to the BBC.
Zookeepers had to lead elephants, flamingos and a hippopotamuses to safety because the fire was blazing over the animals' heads, according to Deutsche Welle.
Gisela von Hegel, director of the zoo, said that there was no possibility of rescuing the petting-zoo animals because the roof had already collapsed, according to the BBC.
The cause of the fire is unknown, but it is being investigated, according to Deutsche Welle.
