Clashes broke out in Senegal's capital Dakar on Wednesday as opposition leader Ousmane Sonko was arrested ahead of a scheduled court appearance to face a rape charge. Sonko, a 46-year-old devout Muslim who is popular with youngsters, had been heading to court to face a charge that he says is politically motivated. Hundreds of people followed his motorcade, sounding car horns and singing traditional songs. But opposition supporters and security.
