The incident occurred in March 2020 in Libya, a country that was in the midst of a civil war. Turkey, a key combatant in the war, deployed the STM Kargu-2 drone, according to the UN Security Council's Panel of Experts on Libya report. The drone, which the report refers to as a "lethal autonomous weapon," then found and attacked Libya's Haftar Armed Forces.
Logistics convoys and retreating forces were "hunted down and remotely engaged by lethal autonomous weapons systems such as the STM Kargu-2," the report reads. "The lethal autonomous weapons systems were programmed to attack targets without requiring data connectivity between the operator and the munition: in effect, a true 'fire, forget and find' capability."
The creator of the Kargu drone, STM, says the device "can be effectively used against static or moving targets through its indigenous and real-time image processing capabilities and machine learning algorithms embedded on the platform."
Smart people like Elon Musk have been warning about this sort of thing for ages. How long till we end up with "The future of technology"? Not good...
