evidence: Equatorial Guinea asked judges at the International Court of Justice to reject Gabon's claim to several islands in potentially oil-rich waters in the Gulf of Guinea. The African neighbours, both significant oil producers, have asked the United Nations' top court to settle a dispute centring on the tiny island of Mbanié, less than a kilometre long, off the coast of Gabon. [...] The conflict has been ongoing since 1972, when Gabon's army drove Equatorial Guinea soldiers from Mbanié.
