London: A 12 year-old Dutch girl, who did not realise she was pregnant, delivered a baby girl when she was on a school trip.
"Neither the girl nor her family had realised she was pregnant, and there were no external signs to show it," the Telegraph quoted a spokesperson for health services as saying.
The girl is from Groningen in the north of the Netherlands.
She felt violent stomach pain when she was on a day out with her classmates last week.
A supervisor alerted the emergency services and when ambulance staff came they saw the girl was about to give birth, the media report said.
She was taken to a nearby building where she delivered her baby.
Both the child-mother and her newborn, are doing well in the maternity ward of a hospital.
