Libya firm announces closure of major oil field

Libya's National Oil Corporation announced Sunday the closure of production at a major oil field in the country's south, declaring a "force majeure".

"On Saturday... the Al-Fil field was subjected to arbitrary closure attempts, due to the entry of a group of individuals and the prevention of the field's workers from continuing production," the NOC said.

It added that the field was shut down on Sunday -- marking the second closure in a matter of weeks.
