FEW places exemplify the chaos that has enveloped Libya better than the oil ports of Sidra and Ras Lanuf, which have changed hands twice in March. First the Benghazi Defence Brigade (BDB), an Islamist militia, captured them from the forces of Khalifa Haftar, the head of the self-styled Libyan National Army (LNA). Then, as the BDB handed control of the ports to forces aligned with the Government of National Accord (GNA) in the capital, Tripoli, Mr Haftar, who is supported by a rival authority in the east, grabbed them back.
