The deadly disease Ebola is currently ravaging parts of the Congo, killing 546.
Efforts are being made to stop the disease from getting worse and even spreading continents.
But the situation is being made worse by warring factions in the area, some of which are even attacking relief workers.
Médecins Sans Frontières confirmed health workers and patients were forced to evacuate a centre in the east of the DRC after attackers set it alight.
MSF tweeted: “As a result of the burning of the building, it is no longer possible to care for patients there.”
It is believed that no patients or staff were injured in the incident.
WHO has previously warned aid workers face mistrust in the area, fuelled by false rumours about treatments and preference for traditional medicine.
There have been several examples of aid workers being attacked by gunmen.
And Daily Star Online previously revealed incidents like this risk spreading the disease further.
Dr Ashish Jha told us infighting in the DRC risks Ebola exploding in numbers.
He said: “Because of the fighting going on in the area, this outbreak could explode in numbers.
“Fighting stops medical personnel from doing their jobs.
“It only takes then disease to spread into another country, then a whole new set of people could get infected..”
The identity or motive of the attackers is not yet known.
