The detention of a Rohingya civilian by the Arakan Army (AA), accompanied by allegations of mistreatment, is drawing renewed attention to the conduct of non-state armed actors in Rakhine State and raising complex questions under international humanitarian law (IHL).

The case centers on U Ashfaq (Ba) Swiyad Hussein, a 42-year-old trader from Maungdaw Township, who was detained after traveling to Yangon for medical treatment. Community sources allege that he was subjected to physical abuse while in custody—claims that could not be independently verified but are consistent with broader concerns raised by rights monitors.

IHL and War Crimes Risk: Legal Obligations of Non-State Armed Groups

Although the Arakan Army is a non-state armed group, it remains bound by core provisions of international humanitarian law applicable in non-international armed conflicts, particularly Common Article 3 of the Geneva Conventions.

Under these standards, all parties to a conflict are prohibited from:

        • Violence to life and person, including cruel treatment and torture
        • Outrages upon personal dignity, including humiliating and degrading treatment
        • Arbitrary detention without due process

If allegations of torture or inhumane treatment are substantiated, they could constitute serious violations of IHL and potentially amount to war crimes under customary international law.

Legal experts emphasize that accountability obligations apply regardless of whether the actor is a recognized state authority. “The threshold is conduct, not status,” one regional legal analyst noted. “Non-state actors exercising territorial control must adhere to minimum humanitarian standards.”

AA Governance: From Armed Group to De Facto Authority

The case also highlights the evolving governance role of the Arakan Army, which has expanded administrative control across parts of Rakhine State amid Myanmar’s ongoing conflict.

In areas under its influence, the AA has established parallel governance structures, including:

        • Local administrative bodies
        • Informal judicial mechanisms
        • Security and policing functions

This transition—from insurgent force to de facto governing authority—places the group under increasing scrutiny regarding rule of law, civilian protection, and minority rights.

For Rohingya communities, the situation remains particularly precarious. Stateless and historically marginalized, they often lack access to formal legal protections and are vulnerable to arbitrary enforcement measures.

Community sources warn that incidents perceived as discriminatory or punitive risk undermining fragile relations between the AA and Rohingya civilians. “Governance requires legitimacy,” said one observer. “Perceptions of bias or abuse can quickly erode that.”

Family Detention and Collective Punishment Concerns

Reports that Hussein’s wife—who is seriously ill—and their son were also detained raise additional legal concerns, particularly regarding collective punishment, which is prohibited under international humanitarian law.

The detention of family members without clear legal basis could further complicate the AA’s compliance with humanitarian norms and deepen fears among Rohingya residents.

Border Security and Trafficking Nexus

The timing of the detention coincides with intensified anti-smuggling operations along the Rakhine coast, including reported seizures of narcotics trafficked via maritime routes between Bangladesh and Myanmar.

These developments point to a broader security–humanitarian nexus:

        • Expanding trafficking networks exploiting porous borders
        • Increased enforcement by armed actors and local authorities
        • Risk of wrongful association of civilians with illicit networks

Analysts caution that counter-trafficking efforts, while necessary, may inadvertently lead to overbroad enforcement in contexts where due process safeguards are weak.

“Distinguishing between victims, civilians, and criminal actors is extremely difficult in such environments,” said a regional security expert. “Without transparent procedures, the risk of arbitrary detention increases.”

Bangladesh–Myanmar Dynamics: Spillover Risks

The case also reflects wider tensions along the Bangladesh–Myanmar frontier. With over one million Rohingya refugees residing in camps in Cox’s Bazar, cross-border movement—both legal and irregular—remains a sensitive issue.

Bangladesh authorities have intensified border monitoring to curb trafficking and unauthorized crossings, while humanitarian actors warn that restrictive policies may push vulnerable individuals toward riskier routes.

The interplay between:

        • Conflict in Rakhine State
        • Refugee conditions in Bangladesh
        • Regional trafficking networks

creates a volatile environment where security measures and humanitarian concerns frequently intersect.

Accountability and the Path Forward

Human rights observers stress the need for transparent investigation mechanisms into allegations of abuse and clearer procedural safeguards in detention practices.

Key recommendations emerging from legal and policy experts include:

        • Establishing minimum due process standards in areas under AA control
        • Ensuring independent monitoring of detention conditions
        • Strengthening community engagement to reduce mistrust
        • Enhancing cross-border cooperation to address trafficking without criminalizing civilians

Conclusion

The detention of a Rohingya civilian by the Arakan Army underscores the complex realities of governance, conflict, and law in contemporary Rakhine State.

As non-state actors assume greater administrative roles, their conduct is increasingly measured not only by military effectiveness but by adherence to legal norms and protection of civilian populations.

For Rohingya communities—already among the most vulnerable—the stakes are immediate: protection, dignity, and the assurance that seeking safety or medical care does not result in detention or harm.
