At least three people have been killed and nine others wounded, when the paramilitary Rapid Support Forces (RSF) launched a drone attack on a central Sudanese city, as fighting intensifies across the vast strategic region of Kordofan that could determine the war's outcome. The strike hit a square near a police station in the Tayba neighbourhood of el-Obeid on Saturday afternoon, military sources told Al Jazeera. Several of the wounded are in critical condition, they said.
