TUNISIA last night lined up an African Nations Cup semifinal showdown with Zambia after clinching a penalty shoot out victory over Gabon in Durban.

The two sides were locked at 1-1 after extra time but Tunisia came out on top by winning 4-1 - in the spot-kick competition.

Gabon, who had dominated the quarter final, missed their first two penalties and sharp shooting from Adel Sellimi, Soufyane Fekih and Mehdi Slimane meant that goalkeeper El Ouaer was able to seal the match when he scored with Tunisia's fourth penalty.

Leeds striker Tony Yeboah earlier gave favourites Ghana a 1-0 victory over 10-man Zaire with a 23rd minute winner in a heated quarter final in Port Elizabeth to set up a last four clash with hosts South Africa.

But Yeboah, who has scored 15 goals for the Yorkshire club this season, was also involved in a controversial off the ball incident when he appeared to elbow Zaire defender Ntumba Danga in the face after 15 minutes of the match.
