Surveillance video of a fatal tiger attack in Beijing has triggered heated discussion on whether zoos should be held responsible if visitors ignore safety reminders.

Saturday's tragedy occurred at Badaling Wildlife World, near the Great Wall in Yanqing district.

Footage released by China Central Television showed a woman being attacked and dragged away by a Siberian tiger after stepping out of a car. Aman and an elderly woman, reportedly the woman's husband and mother, rushed from the car and tried to help her.
