evidence: Sipilou is not actually a town per se, but a commune (low-level administrative division) within the department of Biankouma, Dix-Huit Montagnes Region. A town called Samapleu (7°46'N, 7° 56'W), which is apparently located within Sipilou Commune, is about 15km from the border, so perhaps this is the "town of Sipilou" mentioned in the articles. This would place the disputed village along the stretch of the border that runs south from the Bafing before turning west. However, I haven't been able to turn up any places named "Kpeaba" (or anything similar in maps of that area).
