CAIRO (AP) — Sudan’s military and allied armed groups have staved off an attack by a paramilitary group and Arab militias on a major city in the western region of Darfur, officials and residents said on Saturday.

The attack on Friday was the latest by the Arab-dominated Rapid Support Forces against el-Fasher, the provincial capital of North Darfur province, where hundreds of thousands of people are sheltering, many of them having fled fighting elsewhere in Darfur.

The RSF, which has been at war with the military for more than a year, has built forces up in recent months to wrestle control of el-Fasher, the last city that is still held by the military in the sprawling Darfur region.

Sudan’s conflict began in April last year when soaring tensions between the leaders of the military and the RSF exploded into open fighting in the capital, Khartoum and elsewhere in the country.
