Doctors have successfully separated conjoined twin sisters fused at the liver and chest - the smallest pair ever to survive surgery.
Five surgeons, assisted by two nurses and six anaesthesiologists, carried out the successful, five-hour operation to separate the tiny identical twins at a hospital in Bern, Switzerland.
Maya and Lydia were born two months prematurely along with their triplet sister Kamilla in December.
They were initially stable and doctors at Inselspital hospital, Bern, had planned to allow them to settle after birth and separate them after a few months.
But after a week, their situation deteriorated dramatically: one suffering from hypertension and the other suffering from the opposite condition, known as hypotension.
