Military units are on alert in Cameroon ahead of the expected nationwide protests on Tuesday.
Opposition leader Maurice Kamto's Cameroon Renaissance Movement is calling for peaceful protests, with demands that include the resignation of President Paul Biya, election reform and better representation for undeserved groups, especially in the Anglophone regions.
In an apparent attempt to discourage participation in the protests, the government is reportedly threatening participants with jail time.
Violent clashes between security forces and those demanding rights for the Anglophone regions has prompted thousands of people to flee their homes in recent years.
