Unidentified attackers killed two Ebola health workers in eastern Congo over the weekend, the health ministry said, the latest in a string of assaults that have hampered efforts to stop the deadly spread of the virus.
Local mistrust of health officials and militia violence in Congo's restive east have caused the number of new cases to surge. Nearly 2,500 people have been infected and more than 1,600 killed in the second biggest outbreak on record.
