The second Group A game of the day had its share of opportunities, but neither side was able to break the deadlock.
Moroccan playmaker Younes Belhanda almost forced a winner as he dribbled through the Angolan defence, but dragged narrowly wide.
Angolan debutant Guilherme Afonso nearly punished Morocco keeper Nadir Lamyaghri’s fumble, only to lob wide.
