In this scenario Nigeria and Cameroon undertake a joint initiative to clear Boko Haram elements from vilages along its joint border.
The villages are Siyara, Kote, Sigawa, Bulabundibe, AdeleKe, Tchatike and Lamukura. However, I don't know where they are and I can't find them on Google Maps. As such I have just guesed and so it might look a little odd to anyone that knows where they are. However, none of the reports mention anything about where they are, they all repeat the same thing although there do appear to be quite a few photos.
Also, not sure that Boko Haram put up much resistance though.
