UN investigators raise alarm over Syrians detained inside Syria

Forty nine Syrians, including two children, were reportedly in Israeli military custody by the end of June after being arrested inside Syrian territory. Fionnuala Ní Aoláin, a member of the International Commission of Inquiry on Syria, told the UN Human Rights Council in Geneva on September 9 that the group was subsequently taken to Israel.

The commission said the circumstances could amount to war crimes. Investigators have not been given access to the detainees, and their families have little reliable information about where they are being held or their condition. Israel has denied access, according to Ní Aoláin.

The allegations place a cross border detention operation at the centre of renewed scrutiny of Israel's military activity in Syria. The commission's findings do not represent a ruling by a court, and Ní Aoláin stressed that she was speaking under a mandate from the Human Rights Council, not on behalf of the UN as a whole.

Her account nevertheless gives the case an immediate international dimension. Geneva, home to the Human Rights Council and major humanitarian organisations, has become the main forum for documenting the alleged transfers and pressing for information about the detainees.

Israeli checkpoints and military positions have reshaped daily life for Syrian civilians in the affected areas, investigators said. Ní Aoláin and fellow commissioner Monia Ammar visited the area in July. After that visit, Ní Aoláin condemned what she described as a network of temporary checkpoints and military positions established by Israel.

She said hundreds of people had been questioned and detained. The commission also reported that homes had been destroyed and described Israeli military activity over the past two years as increasingly sustained and entrenched. Ní Aoláin said the measures had significantly affected civilians, adding to the pressure created by displacement, insecurity and restricted movement.

The investigators also raised concerns about the expansion of Israel's occupation in Syria. Their statement comes amid continuing uncertainty over the legal status and practical consequences of Israel's military presence in Syrian territory.

For civilians, the issue is immediate rather than diplomatic. Checkpoints can limit access to work, schools, medical care and relatives. The commission's account does not provide a complete list of those detained or specify the locations of all military sites. It does establish a pattern that investigators say requires further scrutiny and accountability.

More than 1,500 people were killed in last year's violence in Suwayda, and investigators still lack information about many who disappeared. The International Commission of Inquiry on Syria said in March that acts amounting to war crimes had been committed during the violence. Ní Aoláin and Ammar renewed their concern about people reported missing or detained after the fighting.

The uncertainty extends beyond the alleged Israeli transfers. Thousands of Druze remain displaced, while local and national authorities remain locked in disagreement over how to address the situation, Ní Aoláin said. That deadlock continues to fuel insecurity despite efforts by the Syrian government.

The commission also criticised Damascus over the detention of thousands of people accused of links to the ousted regime of Bashar al Assad. Syrian authorities said thousands of investigations or prosecutions were under way. Ní Aoláin said Syria faced immense challenges in establishing a credible rule of law, including the need to review whether those detentions are lawful.

Taken together, the investigators' findings describe several overlapping detention crises. Missing persons, alleged abuses by armed actors and weak legal safeguards continue to obstruct accountability across Syria.

More than 2,000 people, mainly women and children, remain held in Roj camp in north-eastern Syria over alleged links to jihadist groups. Ní Aoláin called the camp's detention system the largest-scale arbitrary detention on security grounds currently taking place anywhere in the world. She added that more than 100 children were being held at military sites.

The commission's criticism of Roj shows that its concerns extend across borders and armed factions. The investigators are challenging Israel over the alleged transfer of Syrians into Israeli custody, while also demanding legal review of detention practices by Syrian authorities and the international coalition's wider security arrangements.

The issue is especially acute for children, who can spend years in detention without a clear judicial process or a practical route home. The commission's statement did not offer a timetable for releases, prosecutions or repatriations. It did underline the scale of the problem and the continuing gap between security claims and legal safeguards.

For Geneva based humanitarian agencies, these cases add to an already extensive record of unresolved detention, disappearance and displacement. Each file requires access, identification and an independent assessment of the evidence against the person held.

The investigators' warning puts access to detainees and credible legal review at the centre of the next phase of international engagement with Syria. Switzerland has followed Syria's transition closely since the fall of the Assad regime in late 2024, and Geneva remains a key diplomatic and humanitarian hub for the country. The allegations therefore carry direct relevance for Swiss institutions and organisations working on accountability, displacement and humanitarian access.

The commission has not disclosed the names of the 49 people reportedly transferred to Israel, nor the sites where they may be held. Those gaps limit independent verification and leave relatives dependent on partial or unofficial information. Israel's reported denial of access adds to the urgency of establishing a mechanism that can verify identities, locations, health and legal status.

The same principle applies to detainees held by Syrian authorities and those confined in Roj camp. Investigators say authorities must distinguish lawful prosecution from detention without due process. They also need to account for people who disappeared during the violence in Suwayda and elsewhere.

The commission's findings will keep pressure on governments and international bodies to provide records, permit access and clarify responsibility. In Geneva, the next test will be whether documentation produces practical protection for the people whose whereabouts remain unknown.
