The United Nations sanctions against Libya imposed in April 1992 under Security Council Resolution 748 were lifted in September 2003, which increased traffic through the Port of Tripoli and had a positive impact on the city's economy. Libyan civil war In February and March 2011, Tripoli witnessed intense anti-government protests and violent government responses resulting in hundreds killed and wounded. The city's Green Square was the scene of some of the protests. The anti-Gaddafi protests were eventually crushed, and Tripoli was the site of pro-Gaddafi rallies. The city defenses loyal to Gaddafi included the military headquarters at Bab al-Aziziyah (where Gaddafi's main residence was located) and the Mitiga International Airport. At the latter, on 13 March, Ali Atiyya, a colonel of the Libyan Air Force, defected and joined the revolution. In late February, rebel forces took control of Zawiya, a city approximately to the west of Tripoli, thus increasing the threat to pro-Gaddafi forces in the capital. During the subsequent battle of Zawiya, loyalist forces besieged the city and eventually recaptured it by 10 March. As the 2011 military intervention in Libya commenced on 19 March to enforce a U.N. no-fly zone over the country, the city once again came under air attack. It was the second time that Tripoli was bombed since the 1986 U.S. airstrikes, and the second time since the 1986 airstrike that bombed Bab al-Azizia, Gaddafi's heavily fortified compound. In July and August, Libyan online revolutionary communities posted tweets and updates on attacks by rebel fighters on pro-government vehicles and checkpoints. In one such attack, Saif al-Islam Gaddafi and Abdullah Senussi were targets. The government, however, denied revolutionary activity inside the capital. Several months after the initial uprising, rebel forces in the Nafusa Mountains advanced towards the coast, retaking Zawiya and reaching Tripoli on 21 August. On 21 August, the symbolic Green Square, immediately renamed Martyrs' Square by the rebels, was taken under rebel control and pro-Gaddafi posters were torn down and burned. During a radio address on 1 September, Gaddafi declared that the capital of the Great Socialist People's Libyan Arab Jamahiriya had been moved from Tripoli to Sirte, after rebels had taken control of Tripoli. In August and September 2014, Islamist armed groups extended their control of central Tripoli. The House of Representatives parliament set up operations on a Greek car ferry in Tobruk.
