Al-Nusra Front
The group announced its formation on 23 January 2012. The United States designated Jabhat al-Nusra as a foreign terrorist organization, followed by the United Nations Security Council and many other countries. It was the official Syrian branch of al-Qaeda until July 2016, when it became a separate organization. In early 2015, the group became one of the major components of the powerful jihadist joint operations room named the Army of Conquest, which took over large territories in Northwestern Syria. It also operates in neighbouring Lebanon. In November 2012, The Washington Post described al-Nusra as the most successful arm of the rebel forces.
