The birth of a pair of conjoined twins who share a single body has stunned doctors in Suining, Sichuan province. The girls were delivered by caesarean section and weighed 9 pounds. While the twins have separate spines and oesophaguses, they share all other major organs and hence separating them would be impossible, say doctors. The parents of the girls, both migrant farmers, say they had never wanted the child as they were not sure if they were able to afford it but doctors did not detect the abnormality in the baby until a few days before birth. The top priority now for doctors though is to keep the twins alive.
