A Libyan fighter jet flies over the eastern city of Benghazi during a military parade to celebrate the second anniversary of NATO's first military operation in Libya on March 19, 2013. On 19 March 2011, Kadhafi's troops and tanks entered the city and the same day French forces began an international military intervention in Libya, later joined by coalition forces with strikes against armoured units south of Benghazi and attacks on Libyan air-defence systems, after UN Security Council Resolution 1973 called for using "all necessary means" to protect Libyan civilians and populated areas from attack by government forces.
