Fresh protests have erupted in several cities across Senegal, in response to the death of at least 15 people during recent political clashes. The UN and African Union have urged for calm, while the Senegalese government called for an end to the violence. The violence reportedly began after Dakar University students clashed with police, along with supporters of opposition leader Ousmane Sonko. Sonko was arrested in early March on charges of disrupting public order, which many of his supporters claim are politically motivated. The unrest has led to the destruction of shops, cars and buildings in several cities, prompting curfews and a heavy police presence. The Senegalese government has called for dialogue with opposition leaders to end the violence.
