Oil terminals in the northern port cities of Ras Lanuf and Marsa El Brega are now controlled by pro-democracy protesters, Reuters reported on Thursday.
Earlier in the day, ten protesters were killed after government troops attacked the western city of Zuwarah, located 120 kilometers (74 miles) west of the capital Tripoli.
Several eastern cities have now fallen in the hands of demonstrators during 10 days of a revolution that has so far claimed the lives of 1,000 people.
Meanwhile, protesters have torn down Muammar Gaddafi’s “Green Book” monument in the northwestern city of Misrata. The book contained the main tenets of political philosophy developed by the embattled 68-year-old Libyan ruler.
Gaddafi’s regime is facing mounting international condemnation over its brutal crackdown on demonstrators as the death toll from Libya’s revolution rises.
The UN Secretary General Ban Ki-moon has called on embattled Libyan ruler to show restraint and immediately stop the violence against demonstrators.
The UN Security Council has also condemned Libya’s deadly crackdown on pro-democracy protesters.
The African Union on Wednesday strongly condemned the indiscriminate and excessive use of force by Gaddafi’s security forces against demonstrators.
The African body announced that it would dispatch a mission to Libya to investigate the situation there.
