EBOLA: UN worker dies of Ebola in Germany

A UN employee infected with Ebola has died at a hospital in Germany. Doctors at the hospital in Leipzig said the man, 56, died despite receiving experimental drugs to treat the virus.

The outbreak has killed more than 4,000 people since March - mostly in Liberia, Sierra Leone, Guinea and Nigeria.

The World Health Organization described it as the "the most severe, acute health emergency seen in modern times". The US and UK are among countries to have introduced scanning at airports.

•     A Spanish nurse remains in critical condition after becoming the first person to contract the disease outside of Africa last week, although doctors say there are signs of improvement.
