Emmanuel and Steven, two workers from Ghana, sit in their makeshift tent in the parking lot of the airport in Tripoli, Libya, Thursday, March 17, 2011. About 500 Ghaneans are still stranded, hoping that a flight from Accra will come fetch them by the week end. The U.N. Security Council has scheduled a vote early Thursday evening on a resolution that would impose a no-fly zone over Libya. The vote would also authorize U.N. member states to take "all necessary measures" to protect civilians from attacks by Moammar Gadhafi's forces.
