Cluster munitions are weapons that contain multiple explosive submunitions.
Cluster munitions typically open in mid-air and release submunitions that can cover a wide area, causing widespread and indiscriminate harm and damage. While submunitions generally explode in the air or on impact, any that do not explode can present a danger to civilians long after the weapon has been fired.
Landmines are devices placed on or just under the ground, designed to explode when a person is nearby or steps on the device. They can pose a threat for many years after they are placed. Cluster munitions and landmines kill and injure large numbers of civilians and cause long lasting socio-economic problems.
