Close to a million people have now been internally displaced in the Central African Republic. <br /><br /> The number of homeless has doubled since December according to the UN and represents a fifth of the population.<br /><br /> Most left the capital of Bangui to escape the fighting between Muslim fighters and Christian militia with many fleeing to neighbouring countries.<br /><br /> The international airport in Bangui is now a makeshift camp for 100,000 people. Skirmishes in surrounding neighbourhoods have prevented humanitarian groups from accessing the site to help with food and water. <br /><br /> Scores of abandoned homes that once belonged to local Christians litter the countryside. They left after grenade attacks, allegedly by Muslims. <br /><br /> Violence initially flared in March when ex-rebel Muslim leader Michel Djotodia staged a coup and forced the Christian president Francois Bozize into hiding. <br /><br /> Since then, the fighting has escalated, despite the presence of over 5,000 peacekeeping troops from the African Union and France on the ground.
