New figures expose the scale of incommunicado detention and put civilian release at the centre of any peace process
More than 16,000 Ukrainian civilians detained by Russia during the war remain deprived of their liberty, according to a new United Nations estimate. Many are reportedly held without contact with their families and on grounds that do not comply with international law. The figure reveals a vast protection crisis, but the UN’s lack of access to Russian detention facilities means it remains an estimate rather than a verified register of individual detainees.
The number was presented by Claudia Fuentes Julio, the UN assistant secretary-general for human rights, during an informal Security Council meeting convened by Latvia and the United Kingdom. According to the new UN estimate, the total includes civilians detained since Russia launched its full-scale invasion in February 2022.
The UN has not said how many of those believed to remain in custody are adults or children. It has also been unable to inspect detention facilities in Russia, leaving families without an independent mechanism capable of confirming where their relatives are, why they are held or whether they are alive.
Evidence of systematic ill-treatment
UN human rights monitors have interviewed 403 Ukrainian civilian detainees and 910 Ukrainian prisoners of war following their release. Fuentes Julio said 85 per cent of the former civilian detainees and more than 95 per cent of the former prisoners of war reported torture or ill-treatment, often repeatedly.
The accounts include allegations of severe beatings, electric shocks, sexual violence, food deprivation and inadequate medical care. The UN has separately documented the execution of 129 Ukrainian prisoners of war at the beginning of their captivity and the deaths of another 48 in custody as a result of torture, denial of medical treatment or other inhumane conditions.
The organisation’s latest human rights report on Ukraine, covering December 2025 to May 2026, found continuing torture and ill-treatment of prisoners, serious restrictions on fundamental freedoms in occupied territory and repeated Russian refusals to grant independent monitors access.
These findings reinforce evidence examined in earlier European Times reporting on torture prevention, where Ukrainian and civil-society representatives warned that detention abuses were continuing despite extensive international documentation.
Civilians are not prisoners of war
International humanitarian law makes a crucial distinction between prisoners of war and civilians. Civilians in occupied territory may be interned only for imperative security reasons, under procedures that include regular review. They cannot lawfully be seized to punish a community, compel cooperation, suppress political identity or provide leverage in negotiations.
Incommunicado detention can also amount to enforced disappearance when authorities conceal a person’s fate or whereabouts. Beyond the immediate risk of abuse, the uncertainty imposes lasting harm on families who may spend years searching through unofficial lists, former detainee accounts and fragments of information from occupied territories.
Leniie Umerova, a Crimean Tatar human-rights activist who addressed the UN meeting, described being detained on what she called fabricated charges while travelling to visit her ill father in Russian-occupied Crimea. Although a court initially ordered her release, she said she was taken away again and moved through seven facilities in six months. She was eventually released after nearly two years.
Russia’s representative rejected the allegations, said its armed forces complied with international humanitarian law and accused Ukraine of abusing Russian detainees. Moscow characterised the meeting as part of a disinformation campaign.
UN monitoring has also documented violations against Russian and third-country prisoners of war held by Ukraine. About half of the former prisoners interviewed reported torture or ill-treatment, mainly during capture, transit or initial interrogation. The UN said conditions generally improved after prisoners reached established Ukrainian detention facilities, to which monitors have been granted access.
Abuses by Ukrainian personnel require investigation and accountability. They do not diminish Russia’s obligations towards the far larger population it holds, nor do they justify denying monitors access to detention sites.
Release must be part of diplomacy
The new estimate arrives as diplomatic efforts to end the war continue without a comprehensive agreement on detainees. Prisoner exchanges have returned thousands of combatants, but civilians do not fit the same legal category and should not be treated as bargaining assets in military exchanges.
A credible peace process should require the disclosure of all civilian detention sites, access for independent monitors, regular family communication and the release of people held without lawful grounds. Urgent medical cases and those facing heightened risks because of age, disability or health should receive immediate attention.
Investigations must continue even where release is secured. Survivors need medical and psychological care, while families require reliable information, legal support and recognition of the harm caused by prolonged uncertainty.
The figure of 16,000 cannot yet identify every missing person or establish every individual case. Its uncertainty is itself part of the story: after more than four years of full-scale war, the outside world still cannot independently determine who is being held behind Russia’s closed detention system. Making those people visible, locating them and returning civilians home must be treated as a condition of peace, not an issue postponed until after it.
