All 31 people including an "official delegation" to Sudan's war-torn South Kordofan state have been killed in a plane crash.
A Sudan Aviation Authority spokesman said the crash followed an explosion aboard the plane which was carrying the officials to a function marking the Muslim Eid holiday.
He said the plane was landing in Talodi town when an explosion was heard and the plane was destroyed.
Talodi has been a key battleground in the war which began in June last year between the government and ethnic rebels of the Sudan People's Liberation Movement-North.
There was no immediate word on what caused the explosion.
