The health minister in the Democratic Republic of Congo has resigned in protest at the handling of the Ebola outbreak in the east of the country.
In his resignation letter, Oly Ilunga condemned a decision by President Félix Tshisekedi to replace him as the head of the Ebola response team.
He also criticised what he described as outside pressure to roll out a new experimental Ebola vaccine.
The outbreak has killed more than 1,700 people over the past year.
Last week, the World Health Organization (WHO) declared the outbreak an international health emergency.
