An international agreement to ban ‘killer robots’ has been proposed by activists at a meeting organised by the United Nations.

The week-long gathering is the second of its kind this year at UN offices in Geneva to focus on futuristic weapons systems that could conduct war without human intervention.

The Convention of Certain Conventional Weapons (CCW), which is the UN body hosting the talks, has been criticised by some for moving too slowly as the technology required to make such machines advances quickly.

“Killer robots are no longer the stuff of science fiction,” Rasha Abdul Rahim, Amnesty International’s advisor on artificial intelligence and human rights, said in a statement.

“From artificially intelligent drones to automated guns that can choose their own targets, technological advances in weaponry are far outpacing international law,” she said.

“We are calling on states to take concrete steps to halt the spread of these dangerous weapons... before it is too late.”

Some countries are more receptive to a ban on the technology than others.
