The United Nations has announced that a 30th country had signed on to the international convention banning cluster bombs, paving the way for the document to come into force on August 1. In a press statement on Convention on Cluster Munition Secretary General Ban Ki-moon welcomed this major advance on the global disarmament agenda, and said that the Convention's entry into force just two years after its adoption demonstrates the world's collective revulsion at the impact of these terrible weapons. The statement sad, cluster munitions are unreliable and inaccurate. During conflict and long after it has ended, they maim and kill scores of civilians, including many children. Burkina Faso and Moldova were the 29th and 30th countries to sign on for ratification after the Convention was opened for signature in Oslo in December 2008.
