The World Health Organization (WHO) has warned of rising Ebola cases as an outbreak spreads beyond the Democratic Republic of Congo (DRC).

WHO chief Tedros Adhanom Ghebreyesus said the DRC's Ituri Province had confirmed 30 Ebola cases, while Uganda reported two infections in Kampala, including one death linked to travelers from the DRC.

More than 500 suspected cases and 130 suspected deaths are under investigation in the DRC, according to WHO officials.
