Nigeria consolidated their leadership of their 2018 World Cup qualifying group after they beat Algeria 3-1 in Uyo on Saturday.
They have now recorded six points from two matches, while Cameroon are second on two points after they forced Zambia to a 1-1 draw at home.
Zambia are third on a point ahead of Algeria.
The qualifying tournament will resume in August 2017 with Nigeria hosting Cameroon and Zambia at home to Algeria.
After a rather shaky start, the home team took the game to their opponents and they were rewarded after 25 minutes, when the lively Victor Moses was released by his fellow Chelsea mate Mikel Obi to fire past Algeria goalkeeper M’Bolhi.
