BERLIN — A 56-year-old Sudanese man who had been working with the United Nations in Liberia died overnight at the hospital in Leipzig where he was being treated for Ebola, the hospital and the United Nations said Tuesday.

The man was the third patient to arrive in Germany in recent weeks for treatment of Ebola, and the first to die.

The hospital, in a statement quoted by the German news media, gave few details on the victim. But the United Nations Volunteers, an organization based in Bonn, Germany, that recruits people to serve in missions worldwide, identified him as Abdel Fadeel Mohammed Basheer, a Sudanese laboratory technician at the United Nations Mission in Liberia.

The United Nations Volunteers said that Mr. Basheer had been in charge of disposal of medical waste and that he had four children. He fell ill on Oct. 6.
