Cameroon’s longtime leader, and the world’s oldest leader, President Paul Biya, has been sworn in for an eighth consecutive term, vowing to restore order after deadly post-election violence.

In his inaugural speech, Biya promised to stay faithful to the confidence of the Cameroonian people and pledged to work for a ”united, stable and prosperous” country. He expressed condolences to victims of the unrest and blamed “irresponsible politicians” for the chaos, while assuring citizens that “order will reign.”
