United Nations Security Council resolution 659, adopted unanimously on 31 July 1990, after recalling previous resolutions on the topic, as well as studying the report by the secretary-general on the United Nations Interim Force in Lebanon (UNIFIL) approved in 426 (1978), the council decided to extend the mandate of UNIFIL for a further six months until 31 January 1991.
