A panda cub whose birth in China was broadcast live last week on the internet, attracting interest around the world, has died, according to a newspaper report. The cub died unexpectedly at a panda breeding centre in Chengdu in Sichuan province on Tuesday morning, the West China City Daily said. It was thought to be the first giant panda born this year, state media reported.

There were no signs of anything wrong with the cub until it cried out and fell from its mother at about 5am on Tuesday, the report said. The cub was already dead when staff took it from Aibang’s room, according to the article. An autopsy found nothing abnormal in the cub’s internal organs and the cause of its death is still unclear. The breeding base said sudden death in panda cubs is rare, but not unprecedented. There may be similarities with sudden infant death syndrome in human babies, the report said. The cub was born last Friday and the live stream of the birth attracted about 620,000 views. ‘Pregnant’ panda’s false alarm as zoo reveals she’d just eaten too many buns Aibang faked pregnancy in 2014 in order to get more rest and fruit in a better enclosure, a member of staff at the centre told state media two years ago.
