The footage ends there, but the harrowing incident did not. Zoo officials report that Ayna continued trying to get her sister to safety, and was eventually able to scale the wall on the side nearest the crowd. She dropped Amelia off by the footpath before finding another way back inside the security of her enclosure.
Keepers rushed to evacuate the area and the young gorilla was shot with a tranquilizer dart. Zoo spokesperson Sagit Horowitz told Israeli media that the entire "escape" took place over a span of three minutes, adding that the public was never in any danger.
"The gorilla was more scared of people," Sagit told Ynet.co.il.
Amelia was treated by a vet who determined her to be in good enough health to return to her family. Officials say that they plan to reassess the gorillas' enclosure and protocol to prevent similar incidents from happening again.
