The News Agency of Nigeria (NAN) reports that the tightly contested clash took place on Sunday at the June 30 Air Defence Stadium in Cairo.
Clear-cut chances were few in the cagey affair.
The Flying Eagles controlled proceedings in the first half but managed only one shot on target.
Morocco dominated possession in the second half but failed to pose any serious threat to Nigeria’s goalkeeper Ebenezer Harcourt.
With the result, Morocco remain at the top of the group on goal difference, having accrued the same number of points as Nigeria (four).
Tunisia, who earlier defeated Kenya 3-1 in the group’s other fixture, are in third place with three points.
The Flying Eagles will face Kenya in their final Group B match on Wednesday at 4 p.m.
NAN reports that the top four teams from the tournament will qualify to represent Africa at the FIFA U-20 World Cup in Chile, scheduled to take place from Sept. 27 to Oct. 19. (NAN)
