Al Jazeera has obtained rare access to rebel fighters of the Nusra Front, which has been carrying out attacks on Al-Nyrab military airport near Aleppo as part of its fight to topple the government of President Bashar al-Assad.
The US has blacklisted the group, calling it an al-Qaeda-linked organisation. The fighters say they want to establish an Islamic state in Syria.
