Here is a compilation of ISW's ISIS Sanctuary Maps from June 2014 - December 2016.
The pro-Assad forces’ onslaught in Aleppo marks a key inflection point for the war in Syria. Eastern Aleppo’s imminent fall – to a coalition that includes Russia and Iran and its various proxies – will accelerate the war’s destabilizing effects. Jihadists will further improve their position within the Syrian opposition. Fighters aligned with Syrian President Bashar al-Assad will continue committing atrocities against civilians. The Russian and Iranian regimes will grow more emboldened.
ISIS recaptured the historic city of Palmyra in Eastern Homs Province on December 11 following the withdrawal of pro-regime forces, marking the first seizure of a major urban center by ISIS in Iraq and Syria since ISIS last captured Palmyra in May 201
The Iraqi Security Forces (ISF) made significant gains in northeastern Mosul from December 6 to 12, but struggled to advance in the southeast. The ISF ordered a change in tactic on December 4 in order to address the lopsided eastern offensive, attempting to make rapid advances in the southeast rather than grind through neighborhood-by-neighborhood clearing operations. The shift, however, failed drastically when the rapid gains left the ISF open to ISIS counterattacks, resulting in heavy casualties on December 6 and 7. In response, the ISF moved units previously allocated to breach Mosul’s southwestern neighborhoods to reinforce efforts in the southeast on December 10.
The United States and its partners can improve regional security and stability in Eastern Europe by supporting the modernization and reform of the Armed Forces of Ukraine more aggressively. Ukraine has suffered from consistent Russian military aggression since Russia occupied the Crimean Peninsula and militarily intervened in the eastern Ukrainian Donetsk and Luhansk Oblasts in 2014. The overall unpreparedness of the Ukrainian military and its inability to match the capabilities of Russian forces allowed Russian and Russian proxy forces to gain a foothold in eastern Ukraine from which they continue to destabilize the entire country. The Ukrainian armed forces have been partially restructured and strengthened in the face of this constant pressure, enough to stabilize the front lines for a time. They require significantly more support of all varieties, however, if they are to stop the advance of Russia and its proxies permanently, to say nothing of reversing the armed occupation of Ukrainian territory.
Pro-regime forces backed by heavy airstrikes seized at least fifteen districts in Eastern Aleppo City including large parts of the Old City of Aleppo, shrinking the pocket held by opposition forces by more than seventy-five percent. Meanwhile, Russia and the U.S. met in Germany to discuss a potential deal to evacuate all civilians and opposition fighters from Eastern Aleppo City except for members of Jabhat Fatah al-Sham - the successor of Syrian Al-Qaeda affiliate Jabhat al-Nusra.
ISIS lost significant control zones near Mosul, Raqqa, and al-Bab since October 17, 2016. Anti-ISIS forces fully encircled Mosul and penetrated the eastern side of the city. Meanwhile in Northern Aleppo, rival Kurdish-led Operation Euphrates Wrath and Turkish-backed Operation Euphrates Shield encroached on ISIS-held terrain near Raqqa and al-Bab, respectively. Operation Euphrates Wrath forces are positioned 30 km north of Raqqa as of December 8, 2016.
The Council of Representatives met to discuss the 2017 federal budget on December 4 and 5 but failed to put the budget to a final vote .The Iraqi Security Forces (ISF) deployed security forces from Baghdad to northern Iraq, as ISIS spectacular attacks in the capital decreased.
The Iraqi Security Forces (ISF) made limited gains in Mosul from November 28 to December 5, but moved additional assets from Baghdad into the region in order to reinforce current lines of effort in Mosul and improve security in southern Ninewa.
