"We heard gunshots all through the day," says Cameroon voter

Cameroon's President Paul Biya waves to supporters on the campaign trail earlier this month.

(CNN)Voters in Cameroon's troubled north and southwest regions stayed away from Sunday's elections as violence broke out between security forces and armed separatists, residents told CNN.

In the Bamenda capital of the northwest region, where separatists had called on people to boycott the elections, residents said they were afraid to come out from their homes amid gunfire.
"We heard gunshots all through the day. The military was patrolling the streets all day trying to quell the attacks. No one wants to be caught in the gunfire," said Kudi Eric Unji, who lives in Bamenda town, one of the regions the Anglophone secessionists want to turn into another country.
    Ballot boxes in the southwest were half empty as voters stayed away in droves.
    A winner must be announced within two weeks, according to the country's electoral commission.
    Cameroon's President Paul Biya, 85, is contesting for a seventh term and has ruled the country since 1982.
    He has often recorded a landslide victory in past elections.
    He was declared the winner of the 2011 elections by the Supreme Court, which found that he got 77% of the vote, beating out 22 other contenders.

    Violence often erupts in Cameroon's English-speaking provinces, where residents say they have been marginalized by the Francophone-dominated government.
    Tensions deteriorated into a full-blown crisis last year after protests in the regions turned violent.
    But Biya maintains his strong grip on the central African country despite the growing secessionist movement, which has worsened security in the nation.
