"This is a win for our people back home," said Morocco's Soufiane Kourodu.

"We came to this tournament facing several adversities, but our team spirit and desire to win allowed us to get the win."

Hosts Tunisia booked their last semi-final place with an 81-60 victory over the Democratic Republic of Congo.

Makram Ben Romdhane was the stand-out performer for the Tunisians, scoring 22 points and three assists.

Senegal then won the fourth and final last four encounter this evening.

They edged Angola 66-57 to complete the semi-final line-up.

The tournament is set to continue tomorrow with the semi-finals where Tunisia play Morocco and Nigeria take on Senegal.
