The Senegalese capital Dakar has been rocked by a fourth consecutive day of violence in clashes between police and opponents of President Abdoulaye Wade.
They have been protesting against his candidacy in a forthcoming presidential election, claiming his bid for re-election breaks rules on a two-term limit.
Their leaders have vowed to make the country ungovernable if he does not withdraw his candidacy.
At least five people have been killed in disturbances since last month when the country’s top legal body ruled that Wade could stand.
Voting has already begun ahead of the election on February 26, with police and soldiers being allowed to cast their ballots early.
With violence set to continue security forces are likely to be deployed in large numbers until the vote is completed.
