Libya: Migrants' plight 'desperate'

More than 191,000 people have fled the violence in Libya, according to a report by the UN's Office for the Co-ordination of Humanitarian Affairs (OCHA), citing figures from the International Organisation for Migration. People fleeing Libya for Tunisia said they had to pass through dozens of checkpoints on their way from Tripoli, the capital, and that they had been robbed by Gaddafi's security forces.
