There have been clashes between police and protesters in the Senegalese capital Dakar after a court handed down a two-year prison sentence to an opposition leader.

Ousmane Sonko was cleared of raping a woman in a massage parlour but convicted of a separate criminal offence of immoral behaviour towards someone under the age of 21.

It is referred to as "corrupting the youth" in Senegalese law.

Mr Sonko denied any wrongdoing and his supporters see the trial as aimed at stopping him from running in next year's presidential race.
