__________________________________________________________________________________.The United States has declared a militant Syiran rebel group a terrorist organization. The US says the al-Nusra front is another name for al-Qaeda operating in Iraq, despite the group's attempts to portray itself as a legitimate part of the Syrian opposition. It\'s now illegal in the US to provide support to the al-Nusra front, significant parts of Syria\'s largest city of Alleppo are reported to be under the control of the al-Nusra front and other radical Islamist groups.
