Head of the UN nuclear watchdog, Mohamed ElBaradei, has received the Nobel Peace prize in Oslo. The prize was jointly awarded to him and the International Atomic Energy Agency. ElBaradei and the chairman of the Board of Governors of the agency, Yukiya Amano, received gold medals and Nobel diplomas, and will share about a million euros in prize money. ElBaradei said the world had to make nuclear weapons as universally condemned as slavery or genocide.“If we hope seriously to escape self-destruction, then I believe that nuclear weapons should have no place in our collective conscience, and no role in our security. To that end, we must ensure, absolutely, that no more countries acquire nuclear weapons,” he said. Awarded 60 years after an atomic bomb was dropped on Hiroshima, the Nobel committee said the prize was to honour efforts to prevent the spread of nuclear arms and promote the safe use of atomic power.
