At least one protester has been killed in the ongoing anti-government protests in Senegal, according to several reports. The protestor was killed during clashes with the police in Bignona, southern Casamance region, although the cause of death is still allegedly unknown and under investigation. The protests, which now enter into the third day today, are in response to the arrest of opposition figure, Ousmane Sonko, who was arrested for reportedly disturbing public order and participating in an unauthorised demonstration. His arrest comes ahead of a scheduled appearance at a Dakar court on a charge of rape.
