A giant panda who delivered a cub on Thursday actually gave birth to twins but one died, said the Austrian zoo which houses the endangered animals. The minute body was spotted hours later on CCTV as Schoenbrunn Zoo staff monitored the mother and her newborn.
It is still not clear whether the cub was stillborn or died after birth.
The surviving cub - which is yet to be named - was the first panda in Europe to be born after having been naturally conceived in captivity.
