Madagascar's security forces shot at a dissident faction of military police and several hundred anti-government demonstrators protesting on Thursday against the country's continued political crisis, according to Reuters. A Reuters witness said the military police, who have set up barricades leading to their camp in the capital Antananarivo, returned fire. It was not immediately clear if there were any casualties. Political turmoil has rocked the Indian Ocean island for more than a year after President Andry Rajoelina grabbed power in a military-backed coup, hurting foreign investment and dramatically slowing economic growth.
