Djibouti were the surprising semi-finalists given they had been ranked outside the favourite teams who were tipped to progress in the junior tournament.
A 1-1 draw against Tanzania which is their second such result in Group B was enough to seal their place. In their opening match, they had held Rwanda, a side that Serengeti Boys defeated 3-1, to a goalless draw.
It looked like they will defeat the Cubs until Mawa scored the winner in the 89th minute. It was his sixth goal in the competition.
In the second semi-final, Tanzania needed post-match penalties to make it to the final after settling for a 1-1 draw in regular time.
