Migrants sit and take some rest on the tiny island of Lampedusa, Italy, Monday, March 21, 2011. Italy warned Monday that it was facing a refugee and humanitarian emergency, with some 15,000 Tunisians having arrived in recent weeks and fears that the start of U.S. and European airstrikes on Libya could unleash even more migrants. Italy has demanded Europe as a whole share the burden of coping with the immigration flows, saying it shouldn't be expected to cope with alone. As it is, the number of Tunisians on the tiny island of Lampedusa, 4,800 as of Monday, was almost the size of the 5,000-strong population itself. Lampedusa's residents are getting increasingly angry over the government's failure to help ease their burden. They have refused plans to set up a tent camp on the island, saying the migrants should be taken elsewhere. (AP Photo/Giuseppe Giglia)
