Pierre-Emerick Aubameyang's third goal of the tournament allowed Gabon to record a 1-0 win over Tunisia this evening.
The former AC Milan striker found the net in the 67th minute, when he held off a number of challenges before slotting the ball beyond the reach of Tunisian goalkeeper Jeridi.
Tunisia exerted a lot of pressure as time ran out, but they were unable to find a route back into the match.
The result means Gabon progress to the quarter-finals of the African Cup of Nations as winners of Group C.
