Two Ebola clinics burned down in DR Congo

Four people with confirmed cases of the highly contagious virus are still missing after fleeing the scene.

The medical NGO Doctors Without Borders has suspended its work at the epicentre of the Ebola epidemic in the Democratic Republic of Congo.

Two of its clinics were burned down, in the latest attack against aid workers trying to contain the dangerous virus.

Ebola is believed to have killed more than 550 people in the latest outbreak – the worst in DRC history.
