The World Health Organization (WHO) says it is concerned about an outbreak of Ebola in the Democratic Republic of Congo, which has become the largest ever in the country's north-west region.

Fifty-six cases of Ebola have been recorded in the country's Equateur province since the latest outbreak was declared in June.
The WHO's regional director, Matshidiso Moeti, says that some of the cases are in remote areas, which are difficult to access.

She said lessons had been learned since a previous outbreak in the same province in 2018, and that more than 12,000 people had been vaccinated in the past six weeks.

In June, the health authorities declared the end of the worst ever outbreak of the virus in the country, in three north-eastern provinces, which killed about 3,200 people.
