People, who used to work in Libya and fled the unrest in the country, wait in line to receive food, as smoke from burning garbage billows in a refugee camp at the Tunisia-Libyan border, in Ras Ajdir, Tunisia, Sunday, March 6, 2011. The camp, which houses about 5,000 people, was built after shelters at the border couldn't handle the large numbers coming through. (AP Photo/Lefteris Pitarakis)
