Libyan rebels have captured Misrata airport, driving back troops loyal to Col Muammar Gaddafi, reports say, according to the BBC. Hundreds of rebels were celebrating in the streets after pro-Gaddafi forces fled, leaving behind tanks that were set on fire, witnesses said. Meanwhile, explosions were reported in the capital Tripoli on Wednesday, after Nato said its planes had carried out 6,000 missions over Libya since it assumed command of military operations there at the end of March. The air strikes have helped secure rebels in their strongholds in eastern Libya, but observers say it remains unclear to what extent they have loosened Col Gaddafi’s grip on western Libya. The EU plans to open an office in the rebel-held Libyan city of Benghazi to improve the flow of aid for the authorities there.
