Bodies are piling up in the streets of Haiti in the aftermath of an earthquake that has decimated the Caribbean island state. On the ground, survivors of the earthquake - measuring seven on the Richter scale - are struggling to save those still trapped under the rubble. At least a third of the population are now homeless - including the country's president. An estimated three million people will need emergency relief as aid organsations make their way to the scene. The Haitian Red Cross predicts an horrific death toll of around 50,000 while the World Health Organization predicts the sheer numbers of dead may lead to an outbreak of disease.
