Cluster Bombs

Cluster bombs can be dropped from aircraft or fired from the ground. They are designed to break open in mid-air, releasing the sub-munitions and scattering them over an area that can be as large as several football fields.


When sub-munitions explode, they fire hundreds of fragments of metal that travel at the speed of a bullet. Anybody within the area, military or civilian, is very likely to be killed or seriously injured. Unlike landmines, which are designed to maim rather than kill, cluster bombs are much more likely to kill and to cause multiple casualties. Even if a victim lives, they will suffer various injuries such as loss of limbs, burns, ruptured eardrums, blindness and internal complications.

An inaccurate weapon that doesn't always explode on impact

Many sub-munitions fail to explode on impact, and huge quantities are left on the ground, leaving a fatal threat to civilians decades after conflict ends.

In many countries, accidents occur when ordinary people try to move unexploded sub-munitions out of economic necessity, curiosity or social responsibility. Civilians might attempt to clear land for farming or to prevent children from playing with bomblets.

In Afghanistan, for example, shepherds, farmers and children collecting firewood are common victims. In many poor communities, people are often injured trying to salvage bomb containers in order to sell the scrap metal.

A life-saving convention banning cluster munitions

These weapons are illegal under the Convention on Cluster Munitions, which became international law on August 1, 2010. Work remains to encourage every nation to join the Convention and to ensure that States Parties fulfill their obligations.

The U.S. has yet to join the Convention on Cluster Munitions. To join the Campaign to ban this weapon, please visit the U.S. Campaign to Ban Landmines and Cluster Munitions.
