A healthy 32-week-old fetus has been terminated in a tragic mix-up at Melbourne's Royal Women's Hospital.
The Herald Sun says doctors had advised a woman who was having twin boys that one of them had a congenital heart defect that would require years of operations, if he survived at all.
She made the heartbreaking decision to abort but at 2.30pm on Tuesday the wrong baby was injected, terminating the healthy fetus.
The paper says the mother then underwent an emergency caesarian section to end the life of the sick child.
A hospital spokeswoman apologised for the distressing clinical accident and said a full investigation was under way.
