evidence: A Cameroonian senior military officer speaking on condition of anonymity because he was not authorized to speak on behalf of the army told the French News Agency (AFP) that Equatorial Guinean soldiers had crossed the River Ntem that forms the natural border between the two countries and erected milestones in the town of Kye-Ossi on the Cameroonian side. [...] Cameroon Army Chief of Staff General Rene Claude Meka visited the 180 – kilometre boundary and the spot where the beacons had been planted in July last year to see where the Equatorial Guinean encroachment had taken place and condemned the "expansionist ambitions" of neighbouring Equatorial Guinea warning that the Cameroon army will not tolerate "any unlawful intrusion" into Cameroonian territory.
