Two Senegalese opposition figures have been arrested as violence broke out over a high-profile court case involving one of them.
Police officers in the capital Dakar clashed with supporters of Barthelemy Dias and Ousmane Sonko who are both strong critics of President Macky Sall.
Hundreds of people accompanied them to the appeals court for a hearing on Dias' conviction for a fatal shooting in 2011 even as he has accused the authorities of sabotaging his attempt to run for city mayor.
