An Austrian hospital has admitted to amputating the wrong leg of an elderly patient during what should have been a routine procedure.
The Freistadt Clinic, in a small town in Austria, said it was "deeply shocked" and described the incident as a "tragic mistake".
The 82-year-old required surgery to remove his left leg due to previous illnesses.
But surgeons marked up the wrong leg before heading into theatre.
It was only two days later, during a routine bandage change, when horrified nurses found the hospital had made a serious error during the operation.
