A pair of identical twins, who were born deaf, have been killed by Belgian doctors after seeking euthanasia when they found out they would also soon go blind.
In a unique case under the country's euthanasia laws, the 45-year-old brothers, from Antwerp, chose death as they were unable to bear the thought of never seeing one another again.
They were euthanised by doctors at Brussels University Hospital, in Jette, on December 14 by lethal injection after spending their entire lives together.
