Senegal police and protesters clash in first major unrest over vote delay

Student reportedly killed in the northern city of Saint-Louis while security forces and demonstrators clash in Dakar

Security forces and protesters have clashed in Senegal's capital and other cities in the first widespread unrest over the delay to a presidential election that constitutes the one of the country's most significant political crises to date.

Riot police in Dakar fired teargas, stun grenades and what appeared to be rubber bullets at large crowds of protesters who set up roadblocks, burned tyres and threw stones.
