Africa Cup of Nations hosts Cameroon are through to the semi-finals, having brushed aside The Gambia thanks to a Karl Toko Ekambi brace.
The Lyon striker headed the Lions in front just after half time in superb fashion, scoring in the 50th minute from a Collins Fai cross.
He was on hand again seven minutes later as he tapped in from the delivery of Martin Hongla.
The Gambia had a great showing in their first tournament, but they were no match for the hosts, who could have gone on to score more.
Cameroon did well to rise above the passing of eight supporters at their round of 16 game against Comoros to continue where they left off, no doubt helped by the passionate home support.
They will now face either Egypt or Morocco in the semi-final on Thursday, with the final, should they get there, on Sunday, February 6.
