Interview with Jabhat al-Nusra (Al Qaeda) commander:
"Abu al-Ezz, commander, says about Jabhat al-Nusra (al-Qaeda): We are one part of al-Qaeda. Our principles are: Fighting vice, pureness and security. Our affairs and our way have changed. Israel, for example, is now supporting us, because Israel is at war with Syria and with Hizbullah.
"To whom did the U.S. hand those missiles before they were brought to you? Were those missiles first given to the Free Syrian Army by the U.S. and from there to you?
No, the missiles were give directly to us. They were delivered to a certain group. When the road was closed and we were besieged we had officers here from Turkey, Qatar, Saudi Arabia, Israel and the United States."
