BUNIA, Congo (AP) — Angry residents of a town at the epicenter of the Ebola outbreak in eastern Congo attacked and burned a tent that was part of a health center where people are being treated for the virus, the staff there said Saturday. It was the second such attack in the region in a week. No one was hurt in the attack, according to initial reports but as patients ran out to escape the fire, 18 people with suspected Ebola infections left the facility and are now unaccounted for, a local hospital director said.
