The IAF saw significant conflict in 1960, when Belgium's 75-year rule over Congo ended abruptly, engulfing the nation in widespread violence and rebellion. The IAF activated No. 5 Squadron, equipped with English Electric Canberra, to support the United Nations Operation in the Congo. The squadron started undertaking operational missions in November. The unit remained there until 1966, when the UN mission ended. Operating from Leopoldville and Kamina, the Canberras soon destroyed the rebel Air Force and provided the UN ground forces with its only long-range air support force.
