IN the 52 years since World War II, they have caused more death and injury than the combined toll of all nuclear and chemical weapons. Each month, every month, these "dumb" landmines kill, maim or disfigure more than 2,000 people, mostly innocent civilians, worldwide. They're called "dumb" weapons because they do not discriminate between friend and foe, between young and old, between man, woman and child. There is one land-mine for every 16 children in the world, or one for every 48 inhabitants of the planet, says the International Committee for the Red Cross (ICRC), which is spearheading the campaign to ban landmines, particularly anti-personnel mines (APLs). For every mine cleared, 20 more are laid. All just waiting, silently, for their next unsuspecting victim.
