Key Takeaway: Russia, Iran, and Syrian President Bashar al-Assad are continuing to set conditions to attack the U.S. and its primary ground partner - the Syrian Democratic Forces (SDF) - in Eastern Syria while international attention is focused on a possible pro-regime offensive in Idlib Province. Pro-regime forces are amassing in Deir ez-Zour Province and consolidating control over infrastructure that could enable future attacks across the Euphrates River. The Russo-Iranian Coalition likely intends to extract concessions from the SDF and U.S. by threatening kinetic escalation in Eastern Syria. They nonetheless remain prepared to use force if negotiations fail.

Russia and Iran have taken additional steps to set conditions for a potential offensive against the U.S. and its partners in Eastern Syria. The Institute for the Study of War (ISW) previously warned in June 2018 that the Russo-Iranian Coalition is preparing to attack the U.S. and its partnered Syrian Democratic Forces (SDF). Pro-regime forces have taken a number of steps since June that will shorten or eliminate the operational pause required to pivot from operations in Western Syria to a main effort in Eastern Syria.
- Russia may be preparing for cross-river operations in Deir ez-Zour Province. Russian Military Police reportedly assumed control over all frontline checkpoints and river crossings (primarily informal ferry crossings) along the Euphrates River in Deir ez-Zour Province in mid-August 2018.[1] Russia is ostensibly asserting order after increasingly violent disputes between pro-regime forces over revenue from cross-front trade with SDF-held areas. This consolidation also positions Russian Military Police for future operations against U.S. and SDF. Russia can construct temporary bridges at these river crossings to enable military movements across the Euphrates River. It has previously deployed combat engineers with bridging equipment to Deir ez-Zour Province.[2] Russia also claims that personnel from the Russian Ministry of Emergency Situations are currently rebuilding infrastructure in Deir ez-Zour Province.[3] It is possible these personnel could also be used for infrastructure projects to support military operations in Eastern Syria.
- Russia and Iran are consolidating command-and-control structures in Eastern Syria. The Iranian Islamic Revolutionary Guards Corps (IRGC) reportedly arrested the local commander of the regime’s National Defense Forces (NDF) in Deir ez-Zour Province on August 18 after Russian Military Police detained him for several days.[4] The arrests followed several days of violent clashes between militias backed by Iran and the NDF in Deir ez-Zour Province. Russia and Iran are likely reorganizing existing local command structures to exert more effective control over pro-regime forces in Eastern Syria. Russia’s assertion of control over the river crossing likely supports this effort. This consolidation is a necessary step ahead of any upcoming combat operation against the U.S. and SDF in Eastern Syria.
- The Russo-Iranian Coalition also continued efforts to destabilize areas held by the SDF and U.S. Anti-ISIS Coalition in Syria. Pro-regime agents reportedly distributed leaflets calling on civilians to fight U.S. and SDF personnel in Raqqa City on August 23.[5] ISW previously warned that pro-regime forces began infiltrating terrain held by the SDF as early as February 2018. Pro-regime forces are building on tribal networks to disrupt and threaten the U.S. and the SDF.
- Assad still seeks a deal that reintegrates the SDF into the Syrian state. Negotiations between the SDF and Damascus are ongoing. Assad has previously emphasized that the regime would not hesitate to use force if these talks fail.[6] He has thus far refused to meet the terms proposed by the SDF and instead opted to escalate politically in Northern Syria. He is pressing forward with plans to extend nationwide local elections scheduled for September 16 to areas held by the SDF. The Syrian Democratic Council (SDC) - the political wing of the SDF - has rejected the vote and detained multiple candidates for office across Northern Syria.[7] Assad’s political escalation has caused a stalemate in the negotiations with the SDF. The SDF and Assad also remain deadlocked over the control of key infrastructure including utilities, dams, and oil fields in Eastern Syria.[8] The SDF has asserted that it will continue to manage oil and natural gas fields in Deir ez-Zour Province until it reaches a full political settlement with Assad.[9] Assad may apply military pressure to coerce greater concessions from the SDF.
The U.S. has begun to block pro-regime tribal outreach but must still prepare for possible military escalation in Eastern Syria. The U.S. sent a senior delegation to meet with local tribes across SDF-held areas of Eastern Syria in late August. The delegation communicated a renewed U.S. commitment to countering both ISIS and Iran in Syria. The visit is an inflection in the level of local engagement and could indicate the U.S. has decided to retain forces in Syria. The framing of U.S. policy in Eastern Syria as anti-Iran is also an inflection and likely reflects a U.S. effort to start blocking the entrenchment of Iran in Deir ez-Zour Province.[10] This outreach is a positive first step toward consolidating gains against ISIS and blocking the ability of Iran, Russia, and Assad to coopt the SDF. The U.S. must be prepared to defend against a military escalation as well. Renewed U.S. engagement in Eastern Syria could prompt pro-regime forces to abandon their diplomatic effort and escalate militarily instead.
Looking Ahead
Pro-regime forces have reshuffled their force disposition on the western bank of the Euphrates River in Deir ez-Zour Province in areas adjacent to ongoing clearing operations by the SDF against ISIS in the area of Hajin.[11] The full scope of these deployments is unclear at the time of this writing. Further deployments of pro-regime forces along the Euphrates River Valley or Iraqi Popular Mobilization Forces (PMF) along the Syrian-Iraqi Border could be an indicator of an imminent attack against U.S. forces or the SDF. Multiple reported attacks against SDF-held oil infrastructure in Eastern Syria in late August could reflect probing attempts by the Russo-Iranian Coalition. The attacks may alternately be conducted by ISIS. ISW will release a refined assessment of the pro-regime force posture in the coming days.
