The city of Garoua continues to witness protests against the rule of President Paul Biya, while awaiting the results of the presidential election.
Security forces have already dispersed some protesters with tear gas in some parts of the country.
Opposition leader Issa Bakary called on his supporters to carry out protests, accusing the Biya government of trying to change the election results.
The country's election commission will announce the results tomorrow, Monday. But Bakary has already declared himself the winner.
