UN worker dies of Ebola in Germany

United Nations medical worker infected with Ebola has died at a hospital in Germany, the BBC reported.

Doctors at the hospital in Leipzig said the man, 56, originally from Sudan, 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 says the outbreak is the "the most severe, acute health emergency in modern times."
