DAKAR, Senegal (AP) — Protestors have taken to the streets for a third day in Senegal in support of the country’s main opposition leader, who made his first court appearance since an arrest two days ago that has sparked increasingly violent demonstrations. At least three people have been killed. The unrest this week is the worst seen in years in a country known for its stability. Police on Friday fired tear gas to disperse crowds throwing objects at security forces and setting tires on fire near the tribunal where Ousmane Sonko appeared. Armored vehicles were in the streets. Sonko and his supporters say the charges against him are politically motivated.
