Many health workers helping with an Ebola outbreak in the east of the Democratic Republic of Congo are in lockdown in the city of Beni.

Despite calls for them to resume work, the United Nations says it is not safe for them to move around.

This means they are unable to vaccinate people, monitor possible cases and educate the community about the disease.

There was a violent protest in Beni on Wednesday, calling for an end to insecurity. Earlier this week, health workers suspended activities following a deadly rebel attack on Beni.

More than 100 people have died in the current Ebola outbreak in DR Congo, including 35 in Beni.
