Zimbabwean President Robert Mugabe, gestures, during the country's Heroes Day Commemorations, in Harare, Monday, Aug. 13, 2012. Zimbabwe's president says his party's symbol of a raised fist was used to fight colonial-era white rule and is not a gesture of violence toward fellow Zimbabweans. President Robert Mugabe said Monday that the power of the fist symbol helped the party defeat colonial oppression and urged the nation to prepare peacefully for a referendum on a new constitution and elections afterward.
