Conjoined twins joined at the stomach and who shared a heart died in the Turkish Black Sea city of Trabzon, Anadolu news agency reported Thursday. "We have lost both of them," said Professor Haluk Sarihan, Head of Pediatric Surgery at the local clinic. One of the babies had a particularly small lung and the oxygen content in the blood had sunk suddenly despite artificial respiration. The twins were born on March 18 by Caesarean. Doctors had said from the beginning that their chances of survival were very low. --SP 0000 Local Time 2100 GMT
