Eighteen fishermen from Sicily are in jail in Benghazi, accused of fishing in Libya\u2019s waters. And in this part of the Mediterranean, rich in the highly-prized and lucrative red prawn, these kinds of arrests are frequent. Usually the Libyans release the men after negotiations. This time it\u2019s different. General Khalifa Haftar \u2013 the warlord with authority over the east of Libya \u2013 is demanding a prisoner swap: the freeing of four Libyans in jail in Sicily convicted of human trafficking and implicated in the deaths of 49 migrants, in return for the fishermen. For Assignment, Linda Pressly explores a little-known conflict in the Mediterranean - the so-called, \u2018Red Prawn War\u2019 and its fall-out.
