On 28 August 2020, the "BBC Africa Eye" and "BBC Arabic Documentaries" revealed that a drone operated by the United Arab Emirates (UAE) killed 26 young cadets at a military academy in Tripoli, on 4 January. Most of the cadets were teenagers and none of them were armed. The Chinese drone Wing Loong II fired Blue Arrow 7 missile, which was operated from UAE-run Al-Khadim Libyan air base. In February, these drones stationed in Libya were moved to an air base near Siwa in the western Egyptian desert.
