Vote are being counted in Cameroon following Sunday's presidential election in which Paul Biya is seeking to extend his 36-year tenure as head of state.

Observers say the count may take up to two weeks to complete.

The vote has largely passed off peacefully in the majority French-speaking part of the country but three people were shot dead by security forces in Bamenda, in the country's Anglophone region.

Officials claimed the victims were separatists, adding that there had been gunfire throughout the region.

Tens of thousands of people were unable to cast their votes because of insecurity.
