Fans of Equatorial Guinea's national soccer team arrive for their final African Cup of Nations Group A match, against Zambia at Malabo Stadium in Malabo, Equatorial Guinea, Sunday, Jan. 29, 2012.

MALABO, Equatorial Guinea — Zambia beat already-qualified Equatorial Guinea 1-0 in the African Cup of Nations on Sunday to secure first place in Group A and join the co-host in the quarterfinals.

Christopher Katongo scored the winning goal in the 67th minute at the Nuevo Estadio de Malabo as Equatorial Guinea's unexpected run of two opening victories came to an end.

The result meant unbeaten Zambia topped the group, while Equatorial Guinea finished in second place and will face a likely meeting with cup favorite Ivory Coast in the last eight.

The scoreline also eliminated Libya despite a 2-1 win against Senegal. Libya needed Equatorial Guinea to beat Zambia to have any chance of progressing.
