In North Africa people are still being killed by land mines made in the Second World War. The US State Department estimates that there are currently between 85 and 90 million anti-personnel mines hidden in the ground, left over from recent wars. The UN believes there are even more, possibly 200 million. Another 100 million are stockpiled ready for laying in new wars yet to begin. Worst affected from uncleared minefields are the poor and pastoral societies in greatest need of the land to rebuild their countries from the devastation of wars. In many countries, to start ploughing or re-stocking land is to risk being maimed.
