Hiroshima Mayor Kazumi Matsui addressed the Seanad Eireann, the upper chamber of Ireland's parliament, on Wednesday, seeking cooperation over the fight against nuclear weapons and over calls for peace.

Touching on the Japan Confederation of A- and H-Bomb Sufferers Organizations, also known as Nihon Hidankyo, being named as this year's winner of the Nobel Peace Prize, Matsui said, "This must be the time to unite the voices of peace-loving people around the world and strengthen their solidarity for peace."

Hiroshima was devastated by an atomic bomb dropped by the United States on Aug. 6, 1945.
