Senegalese riot police fired tear gas to break up a tense, thousands-strong rally 31 January in Dakar demanding that President Abdoulaye Wade drop plans to seek a third term in office. Opposition groups united under the June 23 Movement (M23), had called for mass resistance after a decision last Friday by the country's top judges allowing 85-year-old Wade to seek a third mandate in the February 26 polls. Thousands had gathered by late afternoon in a square in the working class suburb of Colobane, where tension rose and angry youths hurled rocks at scores of riot police keeping watch from afar.
