Russian Foreign Minister Sergey Lavrov was expected in Chad's capital N'djamena on Wednesday, continuing an African tour that has taken him to Burkina Fasso, Guinea, and Congo Brazzaville. The visits are seen by civil society and analysts as Russia's attempt to establish its troops in the Sahel region after military leaders seized power. The coups sparked ideological differences over the presence of American and French troops in Mali, Burkina Faso, Guinea, Niger and Chad. Moki Edwin Kindzeka reports from Yaounde, Cameroon
