Russian Airstrikes in Syria: June 29 - July 27, 2016

Russia enabled pro-regime forces to complete the physical encirclement of Aleppo City on July 28, isolating the primary nexus of the non-jihadist opposition in Northern Syria. These gains threaten the long-term survival of mainstream opposition groups that could serve as potential partners against ISIS and Syrian Al-Qaeda affiliate Jabhat al-Nusra.

ISW Resources on Jabhat Al- Nusra: Al-Qaeda's Syrian Affiliate

Since 2014, ISW has been tracking Jabhat al- Nusra, the official al- Qaeda affiliate in Syria. ISW believes that Jabhat al- Nusra poses one of the most significant long-term threats of any Salafi- jihadi group. ISW recognizes ISIS and al Qaeda are Salafi- jihadi military organizations with distinct sources of strength and maintains that U.S. strategy must operate against both ISIS and Jabhat al- Nusra simultaneously. Focusing on an "ISIS first" strategy will result in Nusra continuing to grow stronger.

The Competing Campaigns Against ISIS in Northern Syria

ISIS currently faces an unprecedented threat to its core terrain in Northern Syria from an array of competing actors. Nonetheless, the degrading position of ISIS in Northern Syria is poised to ignite further conflict. The terrain vacated by ISIS will likely host renewed competition between Syrian Kurds, opposition groups, and pro-regime forces as well as a geopolitical struggle involving Turkey, Syria, Russia, and the U.S. These conflicts could stall further progress against ISIS in Syria.
