According to Libyan state television, rebel forces detained Gaddafi's eldest son, Saif al-Islam earlier Monday. Another son of Gaddafi, Mohammed, was under house arrest, reports said.
Meanwhile, NBC News reported late Sunday that Gaddafi was planning to leave for Tunisia, while China's state-run news agency added he was planning to fly to Venezuela from Tunisia.
Libya, Africa's biggest holder of crude oil reserves, has the capacity to produce roughly 1.6 million barrels of crude a day. The country has produced approximately 100,000 barrels of oil per day since the civil war began in February.
