GENEVA: More than 500 civilians were killed in drone strikes in Sudan between January and mid-March, with the vast majority killed in the strategic Kordofan region, the United Nations said Tuesday.

The UN rights office said it had noted a sharp increase in the use of drones in Sudan’s civil war, underlining “the devastating impact of high-tech and relatively cheap weapons in populated areas.”

“According to information received, over 500 civilians were killed in such strikes from January 1 to March 15,” spokeswoman Marta Hurtado told reporters in Geneva, highlighting that “the vast majority of these civilian deaths were documented in three states in the Kordofan region.”

Sudan’s southern Kordofan region is currently the fiercest battlefield in the three-year war between the regular army and the paramilitary Rapid Support Forces.

The vast region connects RSF strongholds in the western Darfur region with the army-controlled east.
