Large protests have hit Senegal for a third day as demonstrators burnt cars and clashed with police after the arrest of an opposition leader on Wednesday.
Ousmane 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.
At least one person has died in the rare nationwide unrest.
UN Secretary-General Antonio Guterres has urged protesters and police to refrain from violence in the nation which is one of West Africa’s most stable countries.
On Friday police fired tear gas at Mr Sonko’s supporters who set up makeshift barricades in the capital Dakar where the ground was covered in burnt debris and people chanted “Free Sonko”.
Police blocked motorbikes and mopeds, which are popular among Mr Sonko’s young supporters, from the city’s streets. A supermarket in Dakar’s suburbs was raided on Friday.
“What we are living through in this country is incredible, it is shameful,” one protester said.
