The Boeing airliner bound for the Kenyan capital, Nairobi, took off at 8:44 am local time, losing contact with air traffic control atj Bole International Airport in Addis Ababa, just six minutes later, according to news reports. The plane was reportedly carrying passengers from more than 35 different countries.

Mr. Guterres conveyed his “heartfelt sympathies and solidarity to the victims’ families and loved ones, including those of United Nations staff members, as well as sincere condolences to the Government and people of Ethiopia”.

According to the UN Department of Safety and Security in Kenya, 19 UN staff perished in the crash. The World Food Programme (WFP) lost seven staff, the Office of the High Commissioner on Refugees (UNHCR) lost two, as did the International Telecommunications Union (ITU).

Six staff from the UN Office in Nairobi (UNON) were also tragically killed.

The cause of the disaster is not yet known, although weather conditions were reportedly good and the plane went down in a field near Bishoftu, around 35 miles southeast of the capital.

The UN is in contact with the Ethiopian authorities and “working closely with them to establish the details of United Nations personnel who lost their lives in this tragedy” the Secretary-General stated.
