Cluster bombs are essentially a bigger bombs with dozens or several hundreds bomblets inside which are either dropped from the air by aircrafts or shot out by artillery rockets, and missile systems on the ground. Submunitions released by airdropped cluster bombs are most often called “bomblets,” while those delivered from the ground by artillery or rockets are usually referred to as “grenades.” Cluster bombs are often used to destroy multiple targets, and they are often deployed in tens of thousands over a small area.
Air-dropped or ground-launched, they cause two major humanitarian problems and risks to civilians. First, their widespread dispersal means they cannot distinguish between military targets and civilians so the humanitarian impact can be extreme, especially when the weapon is used in or near populated areas. Many submunitions fail to detonate on impact and become de facto antipersonnel mines killing and maiming people long after the conflict has ended. These duds are more lethal than antipersonnel mines; incidents involving submunition duds are much more likely to cause death than injury.
At least 15 countries have used cluster munitions: Eritrea, Ethiopia, France, Georgia, Israel, Morocco, the Netherlands, Nigeria, Russia (USSR), Saudi Arabia, Sudan, Tajikistan, UK, US, and FR Yugoslavia. A small number of non-state armed groups have used the weapon (such as Hezbollah in Lebanon in 2006). Billions of submunitions are stockpiled by some 76 countries. A total of 34 states are known to have produced over 210 different types cluster munitions. More than two dozen countries have been affected by the use of cluster munitions including Afghanistan, Albania, Angola, Azerbaijan, Bosnia and Herzegovina, Cambodia, Chad, Croatia, DR Congo, Eritrea, Ethiopia, Georgia, Grenada, Iraq, Israel, Kuwait, Laos, Lebanon, Montenegro, Saudi Arabia, Serbia, Sierra Leone, Sudan, Syria, Tajikistan, Uganda, and Vietnam, as well as Chechnya, Falkland/Malvinas, Nagorno-Karabakh, and Western Sahara.
Simply put, cluster munitions kill and injure too many civilians. The weapon caused more civilian casualties in Iraq in 2003 and Kosovo in 1999 than any other weapon system. Cluster munitions stand out as the weapon that poses the gravest dangers to civilians since antipersonnel mines, which were banned in 1997. Until 2008 there was no provision in international law to specifically address problems caused by cluster munitions. Israel’s massive use of the weapon in Lebanon in August 2006 resulted in more than 200 civilian casualties in the year following the ceasefire and served as the catalyst that has propelled governments to attempt to secure a legally-binding international instrument tackling cluster munitions in 2008.ratifications and states acceding to the convention here.
