A teenage student has become the fifth person known to have died in Senegal in protests that followed the arrest of opposition leader Ousmane Sonko on Wednesday.
He was killed on Saturday in clashes between demonstrators and security forces in the southern city of Diaobe.
Protesters had tried to burn down official buildings in the city.
Mr Sonko appeared in court on Friday accused of disrupting public order. He also faces a rape allegation.
He denies the allegations and his supporters say the accusations are politically motivated.
On Friday, following violence in the capital, Dakar, and elsewhere, Interior Minister Antoine Felix Abdoulaye Diome vowed to use "all the means necessary for a return to order".
Speaking on national TV, Mr Diome accused Mr Sonko of "issuing calls to violence".
