The government in Senegal has deployed soldiers throughout the capital, Dakar, as residents brace themselves for more unrest.
On Thursday clashes between security forces and protesters left nine people dead.
It followed the conviction of opposition politician Ousmane Sonko for immoral behaviour. He was sentenced – in his absence – to two years in jail.
Mr Sonko maintains the charges were politically motivated to prevent him from running in next year’s presidential election.
Police have surrounded his house and some social media sites have been blocked by the government.
