Mali has had two armed conflicts with Burkina Faso over a border area, one in 1974-75 and another in 1985. The latter conflict took place in December 1985 and lasted five days; the territory in question was the Agacher Strip, a border region about 100 by 12 miles in size. The matter was referred to the International Court of Justice, which divided the territory in 1988 to the satisfaction of both parties.
During Sankara's rule, tensions with Mali over the mineral-rich Agacher Strip erupted in a brief border war in December 1985. The dispute was settled in the International Court at The Hague a year later, apparently to the satisfaction of both states.
