An Argentine schoolgirl who fell pregnant aged just 11 has become a mother of twin sons.
The unnamed youngster gave birth just a month after celebrating her 12th birthday.
News of the birth comes just a day after it emerged a girl aged nine gave birth to a baby daughter in Mexico on January 27, the same day as the twin boys were born in Argentina.
Zoquipan Hospital: The Mexican hospital where a nine-year-old gave birth to her daughter
A teacher at the Argentinian girl's school was the first to notice her baby bump and inform her mother of her suspicions.
Police in her town of Chilecito, 650 miles north west of the capital Buenos Aires, say they are treating the case as child abuse and have questioned two youngsters aged 16 and 20.
The babies were born five weeks prematurely by Caesarian weighing just 3lb 4 oz each.
Authorities say the girl's sister, aged just 14, gave birth herself three months ago.
Locals have had a whipround to help the two girls' handyman father and housewife mother pay for the cost of raising the newborns.
In Mexico, police are hunting for the 17-year-old father of the newborn girl, after he left their home town to look for work.
More details of the new mother's home life were revealed on Thursday as mother and daughter were allowed to leave the hospital in Jalisco. She was only eight when she became pregnant and is known only as Dafne.
Jorge Villasenor, who works with the state prosecutor's office, said Dafne has 11 siblings. Five of them live with their mother, and and six with their father.
Hospital chiefs revealed that they inserted a contraceptive implant into the girl's arm to ensure she did not fall pregnant again.
Her poverty-stricken mother has told authorities the girl slept willingly with the new-born's father. She never reported him to police because she was not aware he had committed a crime.
The teenage father is said to have offered to let the new mother move in with him, but she refused. He has since left Jalisco state to look for work.
Raymundo Serrano, head of Gynaecology at Zoquipan Hospital where the nine-year-old gave birth, said: "The girl received a subdermal contraceptive implant after her parents signed consent forms. It was administered in her forearm and will be effective for up to three years.'
Mr Villasenor added: 'The girl comes from a dysfunctional family.'
The youngest-ever mother was a five-and-a-half from Peru who gave birth by Caesarean to a 5lb boy named Gerardo in Lima in 1939. Her parents had taken her for an examination after assuming the bump in her tummy was a tumour.
Britain's youngest mum is Amy Crowhurst, of Crawley, west Sussex, who got pregnant aged 12 and had a son, Alfie, at 13 in 2002.
