Banning landmines

In March 1999, the Ottawa Treaty banning anti-personnel landmines became part of international law. Over 80% of countries have signed the treaty, which was the culmination of a five-year campaign and which has saved hundreds of thousands of lives around the world. Louise Hidalgo has been talking to Jody Williams, who co-ordinated the campaign and was later awarded the Nobel Peace Prize for her work.
