RIYADH: On Feb. 19, three aid workers were killed and four others wounded when a convoy carrying food and humanitarian supplies in Sudan’s South Kordofan state was struck by a drone.

The Sudan Doctors Network condemned the attack as “a blatant violation of international humanitarian law.” Yet such incidents are not isolated.

A growing body of evidence suggests they are part of a broader pattern, as the beleaguered rebel Rapid Support Forces increasingly deploy drones — often against defenseless civilians — while reportedly benefiting from financial and military backing linked to Abu Dhabi.

The pattern has been visible in recent weeks. On Feb. 15, a drone strike on a market in Sudari, North Kordofan, reportedly killed 28 civilians and wounded 13. Another strike hit Al-Mazmoun Hospital in Sennar state, killing three more.

The following day, a drone attack on a shelter for internally displaced people in Al-Sunut killed 26 refugees, including 15 children. Two primary schools in Dilling, South Kordofan, were also hit, though no injuries were reported.
