Clash between Cameroon’s army and separatist rebels in the Anglophone region on Wednesday has left at least 10 people dead. This is the deadliest clash since President Paul Biya won a seventh term earlier this week. The conflict between Anglophone separatists who want to create an independent state called Ambazonia and government forces has killed hundreds since last year and emerged as Biya’s greatest security problem in nearly four decades in power.

Threats by the separatists disrupted voting in Cameroon’s two Anglophone regions during the Oct. 7 election, keeping turnout to 5 percent in the Northwest and 16 percent in the Southwest.
