RAS JDIR, TUNISIA - MARCH 12: A man walks through a United Nations displacement camp with his belongings on his head on March 12, 2011 in Ras Jdir, Tunisia. Tens of thousands of guest workers from Egypt, Tunisia, Bangladesh, Sudan and other countries are fleeing to the Tunisian border to escape the fighting in and around the Libyan capital of Tripoli. Men, women and children have descended on Tunisia, creating a humanitarian crisis in the country which itself has only recently toppled its president in an uprising. In Libya Muammar Gaddafi has vowed to fight to the end. (Photo by Dan Kitwood/Getty Images) less
