Western powers tell Libyan forces to withdraw from seized port

"We call for all military forces that have moved into the oil crescent to withdraw immediately, without preconditions," said the statement from the United States, France, Germany, Italy, Spain and Britain.

Forces loyal to Haftar took control of Ras Lanuf, Es Sider, Zueitina and Brega ports, displacing a force that is allied to the UN-backed government in Tripoli.
