World's oldest president reshuffles army as his absence stokes unease

Cameroon's veteran leader Paul Biya - who has not been seen in public for nearly two months - has reshuffled the country's military amid growing concerns over his prolonged stay abroad.

The 93-year-old president appointed officials to key positions within the army and promoted five colonels to the rank of brigadier general.

One of the newly promoted brigadier generals is Raymond Jean Charles Beko'o Abondo, who was immediately reappointed as commander of the elite presidential guard - responsible for protecting Biya - a position he has occupied since 2013.

Such shake-ups are not unusual under Biya's administration, particularly at times of intense public scrutiny or perceived weakness.

After an unexpected coup three years ago in neighbouring Gabon, which toppled the 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.

The circumstances under which the latest changes were made have sparked debate, especially among social media users.
