A freak goal from Khaled Korbi set up Tunisia to make an ideal start to their African Nations Cup campaign.
The midfielder’s intended cross put the Tunisians ahead before half-time, and Youssef Msakni extended their lead in the Group C clash.
Houssine Kharja scored to make for a tense finish in Libreville, but Morocco could not find a leveller.
Tunisia beat Morocco in the 2004 final and again had the measure of their north African opponents.
