(CNN) -- Fighting in Libya started with anti-government demonstrations in February and escalated into a nationwide civil war.
For months, rebel fighters -- who have controlled the eastern city of Benghazi and other areas -- have been trying to move closer toward Tripoli, in the west. They are seeking the ouster of Libyan leader Moammar Gadhafi, who has ruled Libya for 42 years.
International leaders have accused Gadhafi's regime of committing human rights violations and killing civilians. Libyan officials have repeatedly accused NATO of killing civilians in airstrikes.
Here are some key points CNN has reported in the conflict.

About 200 demonstrators protesting the arrest of a human activist take to the streets in the coastal city of Benghazi, witnesses say. Several of them are arrested amid confrontations with police.
