When the cluster munitions convention comes in to force, it will be for affected countries to provide assistance to cluster munitions victims, and to seek support from international partners if necessary. The UK is already one of the world's leading donors to humanitarian demining, and since 2001 the Department for International Development (DFID) has spent over £70 million on clearing landmines, cluster munitions and other explosive remnants of war, and helping victims in the worst affected countries. For example, DFID has contributed over £3.5 million towards clearance of the 40 square kilometres of southern Lebanon contaminated by unexploded cluster munitions during the conflict in 2006. One of our major partners, the Mines Advisory Group, has alone cleared over 17,000 unexploded sub-munitions in southern Lebanon since August 2006, allowing thousands of people to return home safely.
