Who's Paul Biya, world's oldest head of state elected by Cameroon
At 92, Paul Biya became Cameroon's President for a record eighth time. Biya has ruled Cameroon since 1982 and he's currently the world's oldest head of state. Biya's win has triggered clashes between security forces and opposition supporters who say the vote was rigged. Biya rarely appears in public, spending long periods in Europe while his advisers handle government affairs.
