That's it for our coverage of tonight's African World Cup qualifiers.
It was a breathless few hours with five ties reaching their climax.
From Sadio Mane's decisive penalty to Karl Toko Ekambi's late winner for Cameroon, the second legs of the play-offs did not disappoint.
However, Egypt and Nigeria will be among the continental heavyweights to be missing out on a spot in Qatar.
Next up is Friday's croup-stage draw, where we will find out who the African sides will be facing come November.
There will be coverage of that across the BBC - thanks for joining us for all the drama!
