Cameroon's President Biya reshuffles army amid unease at his long stay in Switzerland

• After an unexpected coup three years ago in neighbouring Gabon, which toppled Bongo dynasty sending shockwaves across the continent, Cameroon immediately reshuffled its military leadership.
• Then, while running for a controversial eighth term in power at last year's presidential election, Biya reshuffled the top brass of the army.
• Again in June this year, he promoted several members of the defence and security forces to higher ranks.
