On the eve of a historic vote to begin work on an Arms Trade Treaty in the UN General Assembly's First Committee, 15 Nobel Peace Prize Laureates including the Dalai Lama, Desmond Tutu, Oscar Arias and Amnesty International have called on governments to support the Treaty in order to stop irresponsible arms exports "which are causing the peoples of the world so much pain and destruction". The appeal is contained in a letter released today at the UN.
