The UN General Assembly's Legal Committee (the Sixth Committee) begins debate Thursday on an international anti-cloning treaty. The committee will focus on two versions of the proposed treaty - Costa Rica's draft [PDF] calls for treaty banning all cloning; Belgium's draft would ban the cloning of babies, but allow countries to decide on the use of embryos for research. The Sixth Committee offers a summary of its work on the proposed convention against the reproductive cloning of human beings. An ad hoc committee established to consider the proposed convention has additional background. The UN offers a webcast of the debate. AP has more.
