An international member of the United Nations' medical team who was infected with Ebola in Liberia has died despite "intensive medical procedures", a German hospital said today.

The St Georg Hospital in Leipzig said the 56-year-old man, who has not been named, died of the infection overnight . It released no further details.

The man tested positive for Ebola on October 6 and arrived in Leipzig for treatment on October 9, where he was put into a special isolation unit.

The man was the third Ebola patient to be flown to Germany for treatment.

The first patient, a Senegalese man infected with Ebola while working for the World Health Organisation in Sierra Leone, was taken to a Hamburg hospital in late August for treatment.

He was discharged on October 3 after recovering and returned to his home country, the hospital said.

Another patient, a Ugandan man who worked for an Italian aid group in West Africa, is undergoing treatment in a Frankfurt hospital.
