BUNIA, Congo (AP) — Aid workers rushed supplies Thursday to the center of Congo’s outbreak of a rare type of Ebola virus while beleaguered medical personnel struggled with a lack of equipment, a distrustful population and armed groups in a volatile region.

A white cargo plane with aid donated by the European Union delivered masks, gloves, boots and medications — all of which are in short supply — to the northeastern town of Bunia at the heart of the outbreak in Congo’s Ituri province. U.N.-branded forklifts lifted several cases into trucks.
