In the aftermath of the judgment of a two year prison term for opposition leader Ousmane Sonko on Thursday, violence broke out, according to the Red Cross in Senegal, injuring about 360 persons.

At least 16 people are known to have died in the clashes between demonstrators and security forces in the capital, Dakar, and Mr Sonko's home city of Zinguinchor.

Supporters of Mr Sonko say his conviction on charges of "corrupting" a young woman are politically motivated.

They have condemned what they called the "murderous repression" of the security forces.

On Sunday the situation appeared calm.

The government has restricted access to the mobile internet, to stop what it called "subversive messages" from being shared.
