The boy, named Kiron, was born by Cesarean section on Monday weighing 5.5 kilogrammes in Keshobpur, 135 kilometres from Dhaka, said gynaecologist Mohamad Abdul Bari.

"He has one stomach and he is eating normally with his two mouths. He has one genital organ and a full set of limbs," he said. "He was born from one embryo but there was a developmental anomaly."

The clinic had been unable to determine whether the baby had one or two sets of vital organs, Bari said.

The baby's life was not in immediate danger but he and his mother, 22, had been moved to a larger hospital in nearby Jessore city because large crowds had gathered at the clinic, he said.

"Around 150,000 people gathered yesterday from different areas. It became tough for us to care for the baby. We called police to tackle the situation and they are guarding the hospital in Jessore as well," he said.
