At least 35 nationalities, including 32 Kenyans and 18 Canadians, were among the dead, the airline said. The plane was carrying 149 passengers and eight crew members.

At least one of the passengers was carrying a United Nations passport, and the U.N. World Food Programme confirmed that multiple staffers were among those killed.

“The WFP family mourns today,” Executive Director David Beasley said. “We will do all that is humanly possible to help the families at this painful time.”

With a motto of “The New Spirit of Africa,” the government-owned airline is Africa’s largest and has been aggressively expanding on the continent. It opened a new terminal at its hub in Addis Ababa in January, tripling its capacity.
