U.S. Concern Grows as Türkiye-Syria May Expand Operations Against SDF

The Syrian army’s operations command announced strikes on forces allied with SDF terrorist groups in Deir Hafer, east of Aleppo, following days of troop reinforcements. The area lies south of the Euphrates and has remained a key foothold for armed groups that seized territory during the post-Assad chaos.

SDF elements later claimed a withdrawal from the area, describing it as a goodwill gesture amid foreign mediation. Damascus, however, has continued to urge civilians to evacuate, underscoring its determination to press ahead with security operations.

U.S. Intelligence Sees Broader Campaign

U.S. officials told the WSJ that intelligence agencies assess President Ahmed al-Sharaa has approved a multipronged operation, supported by the Turkish military, aimed at dismantling SDF positions in eastern Aleppo province and potentially extending across the Euphrates River.

Some assessments suggest the operation could remain limited, while others believe Syrian forces are preparing to advance from the west toward the Euphrates and south from the border with Türkiye—moves that would significantly alter the balance on the ground.

Washington Moves to Contain Fallout

U.S. military units arrived in Deir Hafer to assess the situation and engage with local counterparts after days of clashes. U.S. Central Command said its priority is preventing uncontrolled escalation, even as Damascus argues that confronting terrorist groups is essential for national unity.

American officials have warned that a broader offensive could prompt the reimposition of Caesar Act sanctions, while continuing diplomatic engagement to revive stalled integration talks.

SDF Factor Blocks Consolidation

The SDF controlled zone in northeastern Syria remains the main obstacle to the new government’s consolidation of authority. Although a framework agreement was signed last year to integrate these forces into the Syrian military, negotiations have stalled, and armed structures remain intact.

From Damascus’ perspective, the continued presence of SDF elements represents a direct threat to state sovereignty and internal security.

ISIS Prison Risk Cited by U.S. Officials

U.S. lawmakers and military officials argue that expanded fighting could disrupt the guarding of thousands of ISIS detainees currently held in facilities across Syria. Syrian officials counter that allowing terrorist groups to retain de facto control over territory and prisons poses a longer-term and greater security risk.
