Libya has declared force majeure for the country's two biggest oil exports ports, Es Sider and Ras Lanuf, the Tripoli-based state National Oil Corp (NOC) said on Sunday. Oil production flowing to the two eastern ports would be gradually shut down, NOC said in a statement, blaming clashes nearby between armed factions allied to Libya's two rival governments. Only a minimum oil staff would stay on site. Force majeure is a legal waiver for contractual obligations. http://english.ahram.org.eg/News/117959.aspx
