Chelsea duo Victor Moses and John Obi Mikel scored for Nigeria as they continued their perfect start to World Cup qualifying with a 3-1 win against Algeria that left them four points clear at the top of Group B.
Moses was the architect of the win in Uyo as he first punished hesitant defending on 25 minutes, when he burst into the area and saw a weak attempt to clear fall back into his path for him to finish.
Mikel doubled the home side's lead just before break and while Nabil Bentaleb set up a nervy finale, Moses sealed the points in injury time when he blasted home after a counter-attack.
The other game in the group saw Cameroon and Zambia play out a 1-1 draw. Collins Mbesuma put Zambia ahead but Vincent Aboubakar levelled from the penalty spot on the stroke of half-time.
Elsewhere, two goals shortly before half-time put South Africa on course for a 2-1 victory against Senegal, which put Bafana Bafana top of Group D for a couple of hours with four points from two games.
A 43rd-minute Thulani Hlatshwayo penalty was followed up by a Thulani Serero strike in the 45th minute before Cheikh Ndoye pulled a goal back for Senegal in the 75th minute.
But Burkina Faso took over at the summit on goal difference later after they beat still pointless Cape Verde 2-0. Both goals came inside the opening 30 minutes, with Banou Diawara scoring the opener after only two minutes before Prejuce Nakoulma doubled the advantage.
Uganda beat Congo 1-0, courtesy of Faruku Miya's 18th-minute strike, to move top of Group E, with four points from two games. Egypt and Ghana meet on Sunday.
Both matches in Group C ended goalless as leaders Ivory Coast claimed a point away to Morocco in Marrakesh, while Mali were held at home by Gabon.
