Gabon matched Equatorial Guinea's spirited start at the African Cup of Nations after a pulsating atmosphere at Stade de l'Amitie carried the co-host to a 2-0 win over Niger in front of its football-mad president.

Ali Bongo and his first lady Sylvia celebrated like fans as the home team outclassed tournament debutant Niger 2-0 in the first match in Gabon.

Gabon controlled its match from start to finish, with first-half goals from Pierre-Emerick Aubameyang and Stephane Nguema capping its dominance.

Morocco then fell to a surprise defeat - as Senegal did on the opening day - after missing a bunch of chances to go down 2-1 to North African rival Tunisia, which held on despite conceding an 86th-minute goal.
