RAS JDIR, TUNISIA - MARCH 09: Men who recently crossed into Tunisia from Libya are pushed back while trying to get into a food tent in a United Nations displacement camp on March 09, 2011 in Ras Jdir, Tunisia. As fighting continues in and around the Libyan capital of Tripoli, tens of thousands of guest workers from Egypt, Tunisia, Bangladesh and other countries have fled to the border of Tunisia to escape the violence. The situation has turned into a humanitarian emergency as fledgling Tunisia is overwhelmed with the workers. Libyan leader Muammar Gaddafi has vowed to fight to the end.
