A woman who beat odds of 10 million to one has given birth to two sets of identical twins at the same time.
Ashley Ness, 35, welcomed all four babies - two girls and two boys - after a Cesarean section at Massachusetts General Hospital in Boston, US, during the early hours of Thursday morning.
The new arrivals were born after 28 weeks and two days - about 12 weeks earlier than a full-term pregnancy - and mother and babies are expected to remain under the watchful eye of staff in the Neonatal Intensive Care Unit for a further eight weeks, according to a spokesperson for the hospitals.
