KOTHAPET, India 15 Sep (ANA) - The “world’s oldest mum”, 74, is in intensive care – along with her husband, 78 – a week after giving birth to twin girls in India.

After waiting nearly six decades for a child, new dad Raja Rao collapsed while suffering a heart attack, just a day after his wife Erramatti Mangayamma underwent a caesarean section.

The couple married in 1962, and had been childless for 57 years.

Dr Sanakayyala Umashankar, director of Ahalya Hospital in Kothapet, said the surgery went “smoothly, both mother and infants are healthy and have no complications whatsoever.

“However, the mother has been taken to intensive care unit to come out of the stress she had undergone for the last few hours.

"It's another world record."

Hours after their birth, thrilled dad Raja Rao hailed their arrival, saying: “Due to the grace of God and doctors, I am the proud father of two baby girls.

“We are the happiest couple on earth today.”

However, The Times reports, he collapsed one day later and was taken to the Ahalya Nursing Home’s intensive care unit in Guntur, Andhra Pradesh.

The couple have remained in intensive care since their babies, who were conceived by in vitro fertilisation (IVF), were born on September 5.

The home has not revealed why the new mum remains in intensive care, and it has not given an update on Raja Rao's condition.(ANA)
