Militants take over Libya's Bahi, Mabrouk oilfields - security official
Both oil operations were empty after staff were evacuated earlier. Mabrouk had been assaulted last month by Islamist militants claiming loyalty to Islamic State, an attack that killed at least 12 people.
Militants have gained ground in Libya, where two rival governments and their armed forces are battling for control, leaving the North African country in turmoil. The United Nations is trying to negotiate a peace agreement.
