A video taken at a zoo in China on Monday that has gone viral shows a live donkey being fed to tigers in front of the public, an incident that has fueled concerns about the welfare of the animals at the facility and at Chinese zoos in general.

In the video, reportedly shot by a visitor at the Yancheng Safari Park, just outside Shanghai, a group of men in raincoats push a donkey down a wooden ramp into a moat where two tigers pounce on it. At one point the donkey thrashes around underwater.

The footage shows only the beginning of the ordeal, but the South China Morning Post reports that it took a half hour for the donkey to die.
