Amadou Bilo Diallo was hiding in his student dormitory with five roommates and a handful of friends when Senegalese police stormed in and began beating them with batons and shields.

The journalism student said he was lucky to walk away with wounds to his head and feet. Others say they were hospitalized after being beaten or jumping from the upper floors of Diallo's building to escape a fire that broke out amid the violence.
