The Campaign to Stop Killer Robots is urging the United Nations to begin talks about banning the use and development of autonomous weapons systems. Representatives from more than 70 countries are attending a five-day meeting in Geneva of the Convention on Conventional Weapons. Autonomous weapons systems are military robots that can independently search and attack targets based on their programming. They are often called killer robots. The Campaign to Stop Killer Robots is a worldwide coalition of 76 organizations in 32 countries. Members include Human Rights Watch, Amnesty International, Mines Action Canada and the Nobel Women's Initiative. Activists say that support is growing for countries to negotiate a ban on the devices during the yearly CCW meeting in late November.
