Medical authorities in Sudan say at least 22 people have been killed after a drone attack hit two markets in paramilitary-controlled towns in the southwest of the country.

The strikes targeted the markets of Abu Zabad and Wad Banda in West Kordofan state part of the resource-rich Kordofan region that is currently the fiercest battlefield in the nearly three-year war between Sudan’s army and the paramilitary Rapid Support Forces (RSF).

A doctor at Abu Zabad hospital, one of the few medical facilities still serving the area, said two drones struck the markets on Saturday, injuring 59 people.

The war has killed tens of thousands of people, displaced more than 11 million and fuelled what the United Nations describes as the world’s largest displacement and hunger crises.
