Al-Jazeera Video: Rebels face network of 'spies' in Aleppo

"It has been more than two weeks, and neither the Free Syrian Army nor pro-Assad forces have been able to take total control of Syria's second city, Aleppo. Free Syrian Army fighters say they cannot compete with the Syrian army's superior weapons, as protesters across the country urge the international community to provide anti-aircraft weapons. In trying to capture Aleppo, the FSA is not only battling Assad's military, but also facing a network of government sympathisers and spies. Al Jazeera's Anita McNaught was in the city in recent days, and sent this report shortly before speaking to us on the phone."
