LUANDA, Jan. 13 (Xinhua) -- Daniel Cousin scored the lone goal to give Gabon a 1-0 win over Cameroon on Wednesday at the African Nations Cup.

    Cousin, a striker for Hull in the Premier League, had a simple finish in the 17th minute after veteran Cameroon center back Rigobert Song made a defensive error.

    Gabon leads Group D with three points. Tunisia and Zambia play their first matches in another group game later Wednesday.

    Four-time World Cup qualifiers Cameroon, Algeria and Nigeria have all lost matches at the African Cup, while Cote d'Ivoire has drawn.

    The Indomitable Lions dominated early on as Achille Emana's elusive run ended with goalkeeper Didier Ovono turning his shot onto a post in the eighth minute.

    Arsenal midfielder Alex Song almost gave Cameroon the lead a minute later, but failed to connect with Geremi's far-post cross.

    It was largely against the run of the play when Cousin broke the deadlock, taking advantage of Rigobert Song's poor defending and connecting with Roguy Meye's through ball to beat goalkeeper Carlos Kameni with a shot into the bottom left corner.

    Rigobert Song is making a record eighth appearance at the African Cup. Alain Gouamene of Cote d'Ivoire and Egypt striker Hossam Hassan have each made seven.

    Gabon, making its first appearance at the tournament after a 10-year absence, had several chances to finish off the game but failed to take advantage of Cameroon's hesitant defending.

    Cameroon's Samuel Eto'o, a three-time African Footballer of the Year, had a chance to equalize in the 75th after collecting a pass from Jean Makoun but the Inter Milan striker fired wide from close range.
