A UN employee who contracted Ebola has died in a hospital in Germany.
The patient had been transported in isolation for treatment at the St Georg Hospital in Leipzig last week.
The man, who has not yet been named, had contracted the disease while working in Liberia. He tested positive for the disease on 6 October and died in the early hours of Tuesday morning.
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 3 October after recovering and returned to his home country.
The clinic said in a statement: "The patient sick with Ebola fever died during the night in St. Georg Clinic in Leipzig.
"Despite intensive medical measures and maximum efforts by the medical team, the 56-year-old UN employee succumbed to the serious infectious disease." The man's death comes as Heathrow began screening passengers arriving in the UK from the countries most at risk of Ebola on Tuesday.
Health Secretary said the UK could expect to see a “handful” of cases within the coming months.
The World Health Organisation (WHO) has warned the epidemic is the "most severe acute health emergency in modern times", while the number of new cases of the disease is "rising exponentially" in the three hardest-hit West African countries.
