RAS JDIR, TUNISIA - FEBRUARY 28: Two men, one wearing the flag of Tunisia, stand at the border of Libya on February 28, 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 and other countries are fleeing to the border of Tunisia to escape the violence. The situation is quickly turning into a humanitarian emergency as fledgling Tunisia is overwhelmed with the migrant workers. Libyan leader Muammar Gaddafi has vowed to fight to the end.
