Tunisia moved top of a tight Group A following a narrow 1-0 win over visitors Togo in Monastir, while Ivory Coasts were another heavyweights to register a 1-0 home win after edging out Sudan in Group I on Friday.
Youssef Msakni bagged the all-important winner just two minutes into the second half to send his side top as they became level on six points with both Togo and Liberia.
The Tunisians, however, enjoy a much better goal difference with five goals more than second-placed Togo as they become in charge after three games.
Elsewhere, a 34th-minute goal from former Arsenal and Roma forward Gervinho proved enough for Ivory Coast as they beat Sudan 1-0 in Abidjan.
But unlike Tunisia, Ivory Coast now lie in second place of Group I on five points, two off leaders Gabon who host the 2017 Cup of Nations.
In Group L, two fixtures have seen the hosts unable to overcome their opponents, with Swaziland playing out a 1-1 draw with Zimbabwe and Guinea held by Malawi.
Felix Badenhorst gave Swaziland an early second-minute lead, which was cancelled out by an own goal from Ndokuito in the 44th minute.
In the other group game, Guinea played out a scoreless stalemate with Malawi – who are now third of the group.
Swaziland remain top of Group L level on five points with Zimbabwe, while Guinea are now bottom with two.
