Conflict in eastern Democratic Republic of Congo (DRC), where M23 rebels and other armed groups are fighting government forces, is dangerously undermining efforts to combat a cholera outbreak. There has been 'a sharp increase in the number of cholera cases in the armed conflict area of North Kivu' Province, the World Health Organization (WHO) said in a statement. Between 11 June and 1 July some 368 new cases were reported.
