Sekou "Trezeguet" Camara headed Guinea level on 55 minutes after Omer Suliman had given Sudan an early lead in Casablanca. Guinea should have been in the ascendancy after Camara's equaliser, but instead Sudan upped the tempo considerably.

A missed penalty by Maki Saifeldin Bakhit denied them the chance to retake the lead five minutes after the hour mark. Yet the same player found the net 10 minutes later for what would be the winner.

CAF's official Twitter account relayed some images of the action:

It meant Sudan held on and are keeping pace with the hosts in Group A.

There was an early shock in Group B when Namibia performed a smash-and-grab on Ivory Coast in Marrakech. The Elephants bossed possession during the opening 45 minutes but couldn't find a breakthrough:

Their profligacy was duly punished when Charles Hambira netted a 93rd-minute winner. It was tough on Ivory Coast, but Namibia had defended well and played a smart game on the break.

Finally, Zambia overcame Uganda thanks to goals from Lazarous Kambole, Augustine Mulenga and Fackson Kapumbu. Derrick Nsibambi had equalised Kambole's goal, but Uganda struggled to cope defensively.

Zambia proved their quality, while Ivory Coast were a letdown in their first group match. Attention will now turn to defending champions Congo, who face a tough opener against Cameroon on Wednesday.
