Lethal Autonomous Weapons Systems

Lethal autonomous weapons systems (LAWS), sometimes called "killer robots" by critics, are weapons platforms capable of identifying, selecting, and applying force against targets without direct human intervention at the moment of engagement. The category spans loitering munitions, autonomous sentry guns, uncrewed combat aerial and naval vehicles, and software-driven targeting systems. There is no universally agreed legal definition; the International Committee of the Red Cross (ICRC) defines them functionally as weapons that select and apply force to targets without human intervention.

Multilateral debate has taken place primarily under the Convention on Certain Conventional Weapons (CCW) in Geneva. A Group of Governmental Experts (GGE) on LAWS was established in 2016 and has met annually since 2017. In 2019 the GGE adopted 11 Guiding Principles, affirming that international humanitarian law (IHL) applies fully to such systems and that human responsibility for use of force must be retained. Progress toward a binding instrument has stalled, with states such as Russia and the United States opposing a treaty, while a coalition including Austria, Brazil, New Zealand, and most of the Non-Aligned Movement back legally binding rules.

Outside the CCW, the UN General Assembly First Committee adopted resolution 78/241 in December 2023, requesting the Secretary-General to seek views on autonomous weapons; a substantive report followed in 2024. The Campaign to Stop Killer Robots, a civil society coalition launched in 2013, advocates for a preemptive ban.

Core legal concerns include compliance with the IHL principles of distinction, proportionality, and precaution; assignment of criminal and state responsibility (the "accountability gap"); and risks of algorithmic bias, escalation, and proliferation to non-state actors. Documented use of loitering munitions such as the STM Kargu-2 in Libya (reported in a 2021 UN Panel of Experts report on Libya) and Israeli and Russian systems in recent conflicts has intensified urgency around the debate.
