Hundreds of opposition supporters clash with Senegalese security forces in the capital Dakar.<br/> <br />A Reuters witness says police are firing tear gas, while demonstrators hurl rocks in return.<br/> <br />These crowds are demonstrating against President Wade's candidacy for a third term in office ahead of a poll set for Sunday.<br/> <br />Six people have been killed in election-related violence so far.<br/> <br />Tuesday's clashes underscore mounting tension in Senegal, which has enjoyed decades of democracy but is gripped by a row over whether Wade should be allowed to run for a third term.<br/> <br />Wade's rivals say his candidacy is illegal because it breaches rules setting a two-term limit.<br/> <br />And they accuse him of backtracking on his own statements that he would not stand for re-election.<br/> <br />But the President now says he is eligible to run as the limits were added to the constitution after he had started his first term in 2000.<br/> <br />The unrest has also raised concerns over the Interior Ministry's ban on demonstrations - a rule which has drawn criticism from European Union observers.<br/> <br />The E.U. mission has called on all sides to refrain from violence - but also added that Senegalese law technically permits demonstrations when they involve presidential candidates.<br/> <br />Travis Brecher, Reuters
