Holders Egypt have eased into the quarter-finals of the African Nations Cup as Group C winners despite conceding a late equaliser in a 1-1 draw with Zambia.

A last-gasp equaliser from Chris Katongo rescued a point for Zambia but they were eliminated after Cameroon beat Sudan 3-0.

Striker Samuel Eto'o became the highest scorer in the tournament's history when he converted from the spot against Sudan, before adding the third in the last minute.

Egypt's Amr Zaki scored after 15 minutes in another solid display by the defending champions, who finished with seven points, one more than second placed Cameroon.

Egypt were left to rue a string of missed chances and were caught out after a sustained period of pressure when Katongo blasted home from close range in the 89th minute.

Egypt will stay in Kumasi for Monday's quarter-final against the runner-up in Group D, which is to be settled on Thursday.

Eto'o's 27th-minute strike took his tally to 15, overtaking the 38-year-old record of Ivory Coast's Laurent Pokou.

A bizarre own goal by Mohamed Ali Khider effectively ended the contest six minutes later before Eto'o completed the scoring in injury-time, his fifth goal at the 2008 finals.

"We've been very efficient and scored 10 goals in the group stage, I don't know many teams who've done that," said Cameroon coach Otto Pfister.

"We totally dominated the first half and, although we did not put on a great show, I'm happy that we've qualified."
