The Libyan civil war began on 17 February 2011 as a civil protest and later evolved into a widespread uprising. By mid-August, anti-Gaddafi forces effectively supported by a NATO-led international coalition were ascendant in Tripolitania, breaking out of the restive Nafusa Mountains in the south to mount an offensive toward the coast and advancing from Misrata on loyalist-held cities and villages from the north and east.
