The official Libyan news agency said Sunday, April 6, 2014 that the country's main militia in the east has agreed to hand back control of four oil terminals it captured and shut down last summer in its demand for a share in oil revenues. The shutdown has cost Libya millions of dollars. (AP Photo/Hussein Malla, File)
