Illustrative cases from Amnesty International reports 2000 - 2001 - Thousands of people worldwide are killed every year by weapons categorized as ''small arms'' or ''light weapons'' - handguns, assault rifles, sub-machine and machine-guns, grenades, mortars, shoulder-fired missiles and landmines. Many more are injured. Most of the victims are unarmed civilians who find themselves in the path of rival armies or criminal gangs. Transnational networks of brokers, dealers, financiers and transporters are the key players in small arms markets, yet most states do not even register them, let alone require each of their deals to be licenced.
