The ceasefire came into effect at 2000 local time and is intended to stabilise key areas where clashes and security operations had intensified.

The announcement followed negotiations between Damascus and the SDF after Syrian government forces moved into parts of Hasakah province earlier this week.

Those deployments came amid accusations that Daesh detainees had been released from detention facilities, raising fears of renewed militant activity and prompting swift military responses from the Syrian army.

The new accord aims to halt hostilities while allowing security arrangements to be reviewed.

According to Syrian officials, the ceasefire is designed to create space for dialogue and coordination on security, administration and the transfer of certain facilities to state control.

Army units that had advanced toward strategic locations in the Jazira region are expected to suspend offensive operations during the truce, while maintaining defensive positions to prevent instability or militant infiltration.

The agreement reflects a broader attempt by the Syrian government to reassert authority in northeastern regions long controlled or administered by the SDF, which is backed by Kurdish forces and has played a central role in the fight against Daesh.

Relations between the two sides have fluctuated over the years, ranging from tactical coordination to armed confrontations, depending on shifting political and military circumstances.

In recent days, tensions rose sharply after reports emerged that detainees affiliated with Daesh had been released from a prison in Al-Shaddadi.

Syrian military leaders blamed the SDF for the release, arguing it posed a direct threat to national security. The army responded by deploying units to secure prisons and surrounding areas, triggering fears of a wider confrontation.

The ceasefire announcement suggests that both sides are seeking to prevent further escalation, particularly at a time when regional and international attention remains focused on Syria’s fragile stability.

Analysts say the truce could serve as a confidence-building measure if it leads to concrete steps on coordination, detainee management and civilian protection.

For residents of Hasakah and surrounding towns, the ceasefire offers a temporary respite after days of uncertainty. Civilians had expressed concern over troop movements, checkpoints and the possibility of renewed clashes disrupting daily life.

Local sources say humanitarian access and basic services had also been affected by the recent tensions, underscoring the need for calm.

The Syrian defence ministry said the ceasefire would be monitored closely and warned that any violations would be dealt with firmly.

Officials stressed that the truce does not signal a retreat from the government’s objective of restoring full sovereignty over all Syrian territory, but rather reflects a tactical pause aimed at achieving longer-term stability.

The SDF has not issued a detailed public statement on the terms of the ceasefire, but sources familiar with the talks said the agreement includes commitments to avoid provocative actions and to continue discussions through designated mediators.

Previous accords between Damascus and Kurdish forces have often struggled to hold, breaking down over disagreements on governance, military integration and resource control.

Regional observers note that the four-day duration of the ceasefire suggests it is a short-term measure, possibly intended to test intentions and reduce immediate risks rather than resolve deeper political disputes.

Much will depend on whether talks continue beyond the truce and whether confidence can be rebuilt after recent accusations and deployments.

Internationally, the ceasefire may be viewed as a positive signal amid broader concerns about Syria’s security landscape, including the potential resurgence of Daesh cells and the involvement of external actors.

Any reduction in fighting between Syrian forces and the SDF could help refocus efforts on counterterrorism and humanitarian recovery.

As the ceasefire takes effect, attention will turn to whether it holds on the ground and whether it opens the door to more durable arrangements.

For now, the four-day pause offers a narrow but important window to ease tensions in one of Syria’s most sensitive regions and to prevent a new cycle of conflict from taking hold.

The Syrian Arab Army announced that its units launched sweeping operations south of Hasakah, focusing on securing Al-Shaddadi prison and nearby security facilities while tracking down escaped Daesh members. Military officials said the deployments were part of a broader effort to stabilise the Jazira region following recent security breaches.

According to military statements, army units have established checkpoints and cordoned off key routes around Al-Shaddadi to prevent the movement of armed elements. Security forces are conducting targeted searches in residential and rural areas believed to be sheltering Daesh detainees released during the incident.

The army said it considers the SDF fully responsible for the release of Daesh components, warning that such actions directly threaten civilian safety and regional stability. Officials stressed that any lapse in prison security could allow extremist networks to reorganise and launch attacks.

Military sources said Syrian commanders contacted mediators and SDF representatives to coordinate the immediate handover of Al-Shaddadi prison and its perimeter to government internal security forces. These requests were declined, prompting the army to proceed with unilateral security measures.

The operations command confirmed that once security operations are completed, the prison and surrounding facilities will be transferred to the Ministry of Interior. Authorities said this step is essential to ensure unified control over detention centres holding high-risk militants.

Syrian forces also began deploying across wider parts of the Jazira region under a recent agreement between the Syrian state and the SDF. The agreement aims to reduce security vacuums and prevent armed groups from exploiting gaps created by fragmented authority.

Local residents reported increased military presence and patrols as government troops entered strategic zones in and around Hasakah. While some civilians expressed concern about renewed tensions, others said stronger security measures were necessary to prevent extremist violence.

Security analysts warn that Daesh sleeper cells remain active in parts of northeastern Syria despite years of military pressure. The release of detainees, even temporarily, risks reinvigorating militant networks and undermining counterterrorism efforts.

The Syrian army said it would continue operations until all released detainees are apprehended and the area is declared fully secure. Commanders emphasised that restoring state authority over prisons and security institutions is critical to long-term stability.

Officials added that coordination with local communities would be increased to gather intelligence and prevent militants from blending into civilian populations. The army urged residents to cooperate with security forces and report suspicious activity.

The developments come amid a fragile security environment in Syria, where shifting alliances and unresolved conflicts continue to complicate efforts to defeat extremist groups. Control over detention facilities remains a key issue, particularly in regions where multiple forces operate.

Government officials reiterated that any action endangering public safety would be met with firm measures. They stressed that the state would not allow the re-emergence of Daesh under any circumstances.

As operations continue, attention remains focused on whether the arrests will succeed in neutralising remaining threats and whether negotiations over prison control can prevent similar incidents in the future.
