YAOUNDE (Reuters) -Cameroon's President Paul Biya, the world's oldest serving ruler, secured an eighth term in office on Monday, election results showed, triggering clashes between security forces and opposition supporters who say the vote was rigged.
Backers of opposition candidate Issa Tchiroma Bakary, armed with sticks and stones, blocked off roads with debris and burning tyres in the central African country's commercial capital Douala.
