Doctor treating Ebola victims killed during attack in Congo

A doctor was killed and 2 hospital workers were injured on Friday during an attack on a hospital in the Democratic Republic of the Congo while they were working with Ebola virus victims, the World Health Organization announced.

The backdrop: This is not the first attack on a hospital that is treating Ebola victims during the second-largest Ebola virus outbreak on record. WHO has yet to declare its highest alert: "Public Health Emergency of International Concern," despite at least 1,000 cases of Ebola confirmed in the Congo.
