Georges Julien Paul and Kate Foo Kune of Mauritius remain on course to retain their titles after they reached the semi-finals of the men's and women's singles events at the All-African Badminton Championships in Port Harcourt.

Kune will take on Egyptian fourth seed Doha Hany, who overcame Allisen Camille of the Seychelles 21-17, 21-10.
Paul won both of his matches in straight games today to ease into the semi-finals of the men's singles tournament.
The 23-year-old ousted Nigeria's Gideon Babalola 22-20, 21-12 in the last eight.
He defeated Babalola's compatriot Alhaji Aliyu Sheehu 21-15, 21-16 in round three.
Paul will go up against third seed Godwin Olofua of Nigeria for a place in the final.
The event concludes tomorrow with semi-finals and finals.
