A man holds a picture of General Khalifa Haftar during a demonstration in support of “Operation Dignity” in Benghazi in this May 23, 2014 file photo. Growing frustration over the reality of life in eastern Libya, which contrasts with the promises of politicians, is feeding support for Haftar, who has set himself up as a warrior against Islamist militancy and who some also see as their saviour.
