A suspected US-led coalition strike on a military site used by Uyghur fighters in Syria's Idlib province on Saturday night has renewed debate over the future of foreign fighters under the country's post-Assad government .
Sources told The New Arab on that an aircraft believed to belong to the international coalition targeted a military headquarters used by Turkistan fighters, formerly known as the Turkistan Islamic Party, in the al-Zainiya area near Jisr al-Shughour in western Idlib.
The strike came hours after another suspected coalition operation killed a man riding a motorcycle near the Syrian-Turkish border in northern Idlib, according to the same sources.
While no confirmed information has emerged regarding casualties from the strike on the Turkistan fighters' headquarters, Syria TV reported that the site was currently empty and that preliminary reports suggested a leader from Hurras al-Din, the former Al-Qaeda affiliate which dissolved itself in January, may have been killed.
The incidents have once again drawn attention to one of the most sensitive issues facing Syria's new authorities: how to deal with thousands of foreign fighters who fought alongside opposition factions during the country's civil war. Who are the foreign fighters? Foreign fighters in Syria are generally defined as non-Syrians who participated in the conflict through military or security formations.
Over more than a decade of war, Syria attracted fighters from dozens of countries. While many served with groups such as the Islamic State group, others fought alongside armed opposition factions, pro-government forces and the Syrian Democratic Forces.
Research estimates suggest the number of foreign fighters currently in Syria has fallen significantly since the overthrow of Bashar al-Assad in December 2024.
Most estimates place their number at around 5,000, rising to between 8,000 and 10,000 when family members are included.
The majority are concentrated in north-western Syria, particularly Idlib province, and include Uyghurs from China and Central Asia, Uzbeks, Kazakhs and smaller numbers of Arab, African and European fighters. Why is Damascus under pressure? The Syrian government has sought to integrate many foreign fighters into official military structures rather than remove them outright, arguing that abrupt exclusion could create new security threats.
President Ahmed al-Sharaa has repeatedly said the fighters joined the conflict voluntarily and has pledged that they will abide by Syrian law and pose no threat to neighbouring states.
The Ministry of Defence has meanwhile incorporated many foreign fighters into official formations, including the newly established 84th Division, while dissolving several independent foreign-led factions.
However, Damascus continues to face international pressure to dismantle or disarm foreign fighter groups.
Draft US defence legislation for 2026 and 2027 would link future military cooperation with Syria to efforts aimed at disarming foreign fighters and jihadist groups. At the same time, US and coalition forces have continued carrying out strikes against figures accused of links to extremist organisations in north-western Syria.
The issue remains particularly sensitive because some foreign fighters are viewed by Syria's new authorities as allies who played a key role in the campaign against Assad's government, while international actors continue to regard some of the same groups as a potential long-term security threat. Why does Syria want to keep them? Some Syrian officials and former opposition figures argue that bringing foreign fighters under state supervision is safer than forcing them underground.
Mohammed al-Karim, a former opposition commander, told The New Arab that foreign fighters in Syria "enjoy popularity within the army, security services and among the Syrian public supportive of the new government in general".
He added that "the Syrian government hesitates to take any action against them due to their decisive role in battles against the former regime's forces from the earliest stages of the revolution until the regime's overthrow".
Al-Karim argued that the fighters "have accumulated significant military experience and were among the most steadfast during battles against the former regime's forces due to their ideological composition and military expertise", making them "a military reserve for the government, which may still need them".
Some international actors have cautiously backed aspects of this approach. Reuters reported in June 2025 that US officials had accepted, in principle, a Syrian proposal to incorporate around 3,500 foreign fighters, most of them Uyghurs, into the Syrian army, provided the process was carried out transparently.
Supporters of integration argue that fighters operating within state institutions remain subject to oversight and accountability, whereas marginalised fighters could be driven towards underground activity or extremist groups seeking to rebuild their networks in Syria.
