Spain-based striker Karl Etta Eyong scored after six minutes to give five-time champions Cameroon a 1-0 victory over Gabon in a tense Africa Cup of Nations clash on Wednesday in Agadir.
His goal earned Cameroon three points, bringing them level in Group F with title-holders Ivory Coast, who edged Mozambique 1-0 in Marrakesh earlier.
It was the first time Cameroon have beaten central African neighbours Gabon in the AFCON after a loss in 2010 and a draw seven years later.
