Liberia's Election Marred by Violence
Monrovia, November 7, 2011
Opposition supporters set up a burning barricade after Liberian riot police stormed the compound of the opposition Congress for Democratic Change headquarters in the capital Monrovia, November 7, 2011. The police fired tear gas and live rounds as they moved on the headquarters of presidential challenger Winston Tubman before being repelled by United Nations peacekeepers, who have set up a cordon around the building. Tubman is challenging President Ellen Johnson Sirleaf, the country's current president and one of this year's Nobel Peace Prize laureates.
