A Tunisian girl waits for her father to cross the border into Tunisia at the border crossing of Ras Jdir after fleeing unrest in Libya on Feb. 23. Thousands of Tunisians have been fleeing Libya after a bloody crackdown on protests against the rule of Moammar Khadafy. At least 30,000 Tunisians had been living in Libya, and officials fear they could become targets because of Tunisia's role in inspiring uprisings across the Arab world. Tunisia's authoritarian president, Zine el-Abidine Ben Ali, was overthrown in January. (Zohra Bensemra/Reuters) #
