Engaging armed groups to protect the separated, the missing, and the dead requires a mix of humanitarian dialogue, legal obligations under international humanitarian law (IHL), and practical mechanisms that ensure dignity, accountability, and family reunification. The International Committee of the Red Cross (ICRC) stresses that armed actors must be persuaded to respect these obligations, as conflicts in recent years have seen record numbers of missing persons.

1. The Humanitarian Imperative

• Scale of the crisis: In 2025 alone, the ICRC registered over 178,300 new missing person cases worldwide, the highest increase in two decades
• Impact on families: Separation leaves parents without knowledge of their children’s fate, spouses waiting endlessly, and communities destabilised.
• Moral and legal duty: Armed groups, whether state or non‑state, are bound by IHL to prevent family separation, clarify the fate of missing persons, and treat the dead with dignity.

2. Legal Framework

• Geneva Conventions & IHL: Require humane treatment of civilians, respect for the dead, and facilitation of family contact.
• Customary IHL: Obligates all parties to search for the missing and protect remains.
• National laws: Many states incorporate these obligations into domestic legislation, reinforcing accountability.
• ICRC Guidance (2026): Outlines how armed groups can implement obligations—such as recording burials, allowing humanitarian access, and refraining from targeting civilians.

3. Practical Engagement Strategies

• Dialogue with weapon bearers: Humanitarian actors must establish trust, emphasising shared values of dignity and community protection.
• Training and sensitisation: Armed groups should receive structured sessions on IHL, cultural respect, and humanitarian norms.
• Memoranda of Understanding (MOUs): Agreements can define roles, responsibilities, and reporting mechanisms for handling missing persons and remains.
• Joint mechanisms: Involving local communities, religious leaders, and humanitarian agencies ensures compliance and oversight.

4. Protecting the Separated

• Safe zones and checkpoints: Armed groups can facilitate safe passage for civilians fleeing conflict.
• Family tracing services: Cooperation with humanitarian agencies to reconnect separated families.
• Communication channels: Allowing Red Cross messages or supervised phone calls to reduce uncertainty.

5. Addressing the Missing

• Search and documentation: Armed groups must record detentions, transfers, and casualties.
• Transparency: Sharing lists of detainees or deceased with humanitarian agencies.
• Rapid response teams: Joint units to investigate disappearances and prevent enforced disappearances.

6. Dignified Treatment of the Dead

• Proper burial practices: Ensure remains are treated respectfully, with graves marked and recorded.
• Return of remains: Facilitate repatriation to families when possible.
• Forensic cooperation: Allow humanitarian forensic experts to assist in identification.

7. Challenges

• Distrust: Armed groups may fear exposure or prosecution.
• Fragmentation: Multiple factions complicate coordination.
• Resource constraints: Lack of training or facilities to manage the remains properly.
• Political sensitivities: Governments may resist engagement with non‑state actors.

8. Recommendations

• Neutral humanitarian dialogue: Engagement must remain impartial, focusing on human dignity rather than politics.
• Capacity building: Provide armed groups with tools—body bags, registers, forensic kits—to meet obligations.
• Community involvement: Families and local leaders should be part of monitoring mechanisms.
• Accountability: Encourage armed groups to publish reports on missing persons and treatment of the dead.

9. Key Case Law

Key case law emphasises that the duty to search for the missing and protect the dead applies to both states and non-state armed groups:

• Ukraine and the Netherlands v. Russia (ECHR, 2024/2025): Reinforces the “effective control” principle, holding powers responsible for those deprived of liberty or deceased in territories they occupy.
• Ramírez Calderón v. Chile (IACtHR, 2025): Establishes that the failure to investigate the whereabouts of missing persons violates the right to “juridical personality” and “personal integrity” for both victims and their families.
• Resolution 97/2025 (IACHR): Mandates that parties must provide official information on the fate of detainees to prevent “enforced disappearance” during states of emergency.

10. Systematic Disregard: Barriers to Legal Compliance

Despite the clear mandates of IHL, many armed groups operate in a state of systematic defiance. This disregard is rarely accidental; rather, it is the result of several interconnected factors:

• Weaponisation of Suffering: In modern asymmetric warfare, the dead and the missing are often used as “bargaining chips”. Factions may withhold remains to extort political concessions or use enforced disappearances as a psychological tool to terrorise civilian populations and suppress dissent.
• The Accountability Vacuum: Non-state actors frequently operate beyond the reach of formal justice systems, dismissing IHL as a “foreign” or “Western” construct that does not apply to their specific struggle. This sense of immunity is bolstered by the absence of local enforcement mechanisms.
• Fragmented Command Structures: In decentralised conflicts, a “disconnect” often exists between leadership and the frontline. While high-level commanders may pledge cooperation to humanitarian agencies for political legitimacy, individual units often ignore protocols regarding detainee documentation and grave marking.
• Resource and Training Constraints: In many instances, violations are born of incapacity rather than malice. A lack of forensic tools, body bags, or administrative training prevents groups from meeting their obligations, leading to a landscape of “ambiguous loss” for thousands of families.

11. Mechanisms for Accountability

When dialogue fails, the international community relies on several legal and political levers to address violations:

• International Tribunals: Groups and individuals may face prosecution for war crimes, crimes against humanity, or genocide before the International Criminal Court (ICC) or specialised ad hoc tribunals.
• Universal Jurisdiction: This principle allows national courts to prosecute individuals for grave breaches of IHL, regardless of where the crimes were committed or the nationality of the perpetrator.
• Global Sanctions: The UN Security Council can impose targeted sanctions, including travel bans and asset freezes, against leaders who oversee the systematic disappearance of civilians or the desecration of remains.
• Documentation and Reparations: Humanitarian agencies and NGOs continue to document violations, creating a permanent record that serves as the foundation for future truth commissions and victim reparation programmes.

12. Conclusion

Engaging armed groups to protect the separated, missing, and dead is both a humanitarian necessity and a legal obligation. By combining dialogue, training, and oversight, humanitarian actors can persuade armed groups to uphold dignity and reduce suffering. The ultimate goal is to ensure that families are reunited, the fate of the missing is clarified, and the dead are treated with respect—transforming conflict zones into spaces where humanity is preserved even amidst violence.
