Afghan children sit in front of land mines, bombs and mortars at a camp for refugees on the outskirts of Jalalabad, inside Afghanistan, October 31, 2001, as they are taught by a mine-clearing organization about the dangers of various munitions. Afghanistan, which has one of the largest concentrations of landmines in the world, now has to contend with the new hazard of unexploded cluster bombs which have been dropped in U.S.-led attacks over the past few weeks.
