An Antonov plane of the private 'Air Kasai' airline of the Democratic Republic of Congo crashed last night around 50km north of Brazzaville due to still unknown causes, killing 14 people, including 4 crewmembers. Based on first reports released this morning by the Congolese press, the plane took off yesterday at 5:30p.m. local time from Buendé, in the Equator province, en route to the capital Kinshasa. At the time of the crash, the Antonov was flying over neighbouring Congo-Brazzaville. This was the fourth accident involving a DR-Congo airline since the start of September: last Thursday a small plane crashed near Goma, main city of North Kivu, killing the pilot and injuring some passengers; on Wednesday another Antonov of the Galaxie' airline crashed near the airport of Isiro, in east DR-Congo, killing 11 people. The Transport ministry immediately withdrew operations authorisation from 35 of 53 air companies in ex-Zaire for lack of security norms.
