MAPUTO: Police in Mozambique fired tear gas to disperse protesters in the capital Maputo Thursday after the main opposition leader called for a demonstration against election results. The southern African nation has been rocked by violence since an October 9 vote, won by the Frelimo party which has been in power for almost 50 years. Opposition leader Venancio Mondlane, who said the results were false and that he won, called for a mass protest on Thursday, saying in an interview that it was a “crucial moment” for the country.
