Not far from a wildlife protection camp deep in the Qiangtang National Nature Reserve, a wolf on Friday attacked a pregnant Tibetan antelope among a migrating herd, leaving wounds in her stomach and neck.

At the sight of the antelope struggling in the snow, several rangers carried her back to the camp for rescue. Unfortunately, her belly was slashed open and internal organs were damaged beyond cure. The rangers had no other choice but to sew up her belly and send her back to the wild, where she was found dead the next morning.

Every year, tens of thousands of pregnant Tibetan antelopes, a species under first-class state protection in China, start their migration around May for birth-giving and would return with their cubs in late July. Their natural enemies including wolves and bears are always there to ambush them. (Xinhua/Jiang Fan)
