Sudan’s Paramilitary War: Emerging Arms Corridors to South Sudan and CAR

Since mid-2023, Sudan’s intensifying internal conflict—marked by fierce power struggles between the Rapid Support Forces (RSF) and the Sudanese Armed Forces (SAF)—has created a security vacuum in the southern reaches of the country. This has accelerated the emergence of clandestine arms trafficking corridors extending into South Sudan and the Central African Republic (CAR). Intelligence from field operatives, satellite imaging, regional peacekeeping reports, and cross-border monitoring confirm that these corridors are now fueling armed violence, strengthening insurgent factions, and disrupting fragile peacebuilding efforts in neighboring countries.

The RSF, leveraging its territorial control over Darfur and parts of Kordofan, is believed to be facilitating large-scale arms flows into unstable regions such as Unity and Upper Nile States in South Sudan, and Vakaga and Bamingui-Bangoran prefectures in northern CAR. These weapons—ranging from assault rifles and machine guns to rocket-propelled grenades and surveillance drones—are falling into the hands of rebel militias, ethnic militias, and warlords. In response, international peacekeeping missions, such as the United Nations Mission in South Sudan (UNMISS) and the United Nations Multidimensional Integrated Stabilization Mission in the Central African Republic (MINUSCA), are facing increasing difficulty in containing escalating violence.

“Sudan’s war is bleeding far beyond its borders. These corridors are not just routes of rifles—they are highways of instability, connecting fragile states to a growing shadow economy of terror.” — Emmanuel Kotin, Executive Director, Africa Center for Counter Terrorism

The Sudan Crisis (2023–2025)

The Sudanese conflict erupted following the collapse of a delicate transitional power-sharing arrangement between the RSF and SAF. Triggered by disputes over military integration, constitutional timelines, and control of state assets, full-scale armed confrontation began in April 2023. As urban centers like Khartoum descended into chaos, the peripheral regions—particularly Darfur and Kordofan—became RSF strongholds, effectively splitting the country into zones of influence.

This fragmentation severely undermined state authority. Central command structures disintegrated, and paramilitary and tribal militias took control of local governance and commerce. In this lawless environment, arms trafficking operations have flourished, turning Sudan into a major arms exporter to volatile regions to the south.

II. Geographic Focus

Strategic mapping reveals several southern smuggling corridors from Sudan into South Sudan and CAR:

• South Sudan Entry Points:

  • Renk (Upper Nile): Primary logistics node for northern convoys

  • Raja and Yambio (Western Equatoria): Paths used by Darfuri traffickers

  • Aweil (Northern Bahr el Ghazal): Linking East Darfur to SPLA-IO rebels

• CAR Entry Points:

  • Vakaga (Birao): Primary destination of convoys from South Darfur

  • Bamingui-Bangoran and Ouadda: Access points for Seleka-linked groups

• Transit Zones within Sudan:

  • Nyala, El Daein, Tulus (South Darfur): RSF-controlled arms departure hubs

  • Kadugli (South Kordofan): Key waypoint for shipments heading southeast

These routes traverse forested terrain, riverine crossings, and unguarded paths, making them difficult to monitor.

III. Weapons Origin and Flow

Commonly Trafficked Weapons:

• Assault Rifles: AK-47s, FN FALs, M4s

• Heavy Machine Guns: PKMs, DShKs mounted on technicals

• Explosives and Launchers: RPG-7s, grenades, IED components

• Drones: Short-range UAVs for surveillance and targeting

• Ammunition: Russian, Chinese, and Iranian manufacture

Transport Tactics:

• Vehicles: Modified pickup trucks with secret compartments

• Pack Animals: Camels and donkeys in inaccessible regions

• Riverine: Boats through the Bahr el Ghazal and White Nile

• Foot Caravans: Small groups avoiding checkpoints and patrols

Weapons are often disguised under agricultural produce, humanitarian aid, or mining equipment to escape detection.

IV. Actors Involved

Sudan-Based:

• RSF Field Commanders and Logistic Cells

• Arab and Zaghawa Militias in Darfur

• Independent Smuggling Syndicates with SAF deserters

Cross-Border Collaborators:

• SPLA-IO Splinters (South Sudan)

• NAS (National Salvation Front) Fighters

• Ex-Seleka and Anti-Balaka Militants (CAR)

• Foreign Mercenaries (including Wagner-linked contractors)

• Gold and Fuel Traffickers Financing Deals

These actors often coordinate informally, driven by profit, ideology, or territorial control.

V. Key Corridors Identified

1. Nyala → Raja → Yambio: Utilized by RSF-aligned militias and gold smugglers

2. Tulus → Renk → Malakal/Upper Nile: Supporting weaponized oilfield disputes

3. Kadugli → Birao → Bria: Sustains Seleka resupply with heavy weapons

4. El Daein → Am Dafok → Ouadda: Gold-for-arms swap zones, with Wagner linkages suspected

These corridors serve dual purposes: arms movement and mineral exfiltration.

VI. Satellite Imagery and Surveillance Gaps

Imagery from commercial and NGO satellite sources highlights:

• Clear tracks of repeated movement through savannah terrain

• Makeshift rest camps at regular intervals

• Lack of surveillance drones from regional or international forces

• Peacekeeping bases situated too far from trafficking choke points

VII. Evidence from Intercepts and Seizures

• Unity State (March 2024): Seizure of 12 rifles, 4 RPGs, and RSF field manuals

• Vakaga (June 2024): MINUSCA patrol intercepts uniforms and small arms traced to El Daein

• Renk (January 2025): Interrogation of arms dealer reveals GPS trails linked to Nyala warehouses

VIII. Humanitarian and Civilian Fallout

• 250,000+ displaced persons since Q2 2023 due to rearmed rebel advances

• Child soldier recruitment resurging in CAR’s northern zones

• Mining areas militarized, pushing out artisanal miners

• Intercommunal massacres in Jonglei and Upper Nile escalate

IX. Peacekeeping and UN Mandate Challenges

• UNMISS & MINUSCA constrained by mandate limitations

• Delayed intelligence-sharing across mission areas

• Understaffed patrols incapable of 24/7 border surveillance

X. Linkages to Regional Jihadist Movements

• ISWAP intermediaries interacting with gold traffickers in CAR

• Wagner’s dual role as security contractor and arms dealer in mineral zones

• Reported resales of arms to Sahel-based jihadist cells

XI. Economic Incentives and Mineral Smuggling

• Sudanese gold used to purchase arms via Libya/Chad corridors

• CAR’s diamonds exchanged for light weapons

• Fuel stations at borders doubling as trade and arms hubs

XII. Case Studies (2023–2025)

1. Nyala-Vakaga (April 2023): Ambushed convoy uncovered RSF manifest

2. Renk (October 2024): UN drone records large arms offload near airstrip

3. South Darfur to Unity (February 2025): Medical aid truck contained disassembled weapons

XIII. South Sudan’s Vulnerabilities

• Security vacuums in Renk, Leer, and Aweil

• SPLA-IO vs SSPDF rivalry leading to arms leaks

• Reintegration program collapse driving youth back to arms

XIV. CAR’s Fragmented Armed Actors

• Ex-Seleka buying Sudanese weapons to contest Ouadda

• Anti-Balaka using arms for mineral control

• Weak CAR state presence in Birao facilitates impunity

XV. Intelligence Failures and Border Monitoring Gaps

• No real-time data exchange between UNMISS, MINUSCA, and AU

• Lack of biometric tracking of cross-border actors

• AU’s Early Warning System largely dormant in this region

XVI. Forecast (Q3 2025–2026)

• Expansion of arms flows to Jonglei and Lakes states

• Emergence of hybrid warlords commanding forces in both South Sudan and CAR

• Use of corridors by jihadists to bypass Sahel surveillance zones

XVII. Recommendations

• Establish tri-border surveillance unit under AU-UN command

• Launch digital arms-tracking program in cooperation with ECOWAS and IGAD

• Target mineral-trade nodes financing trafficking networks

• Enhance peacekeeper mobility with rapid-deployment air support

The unchecked proliferation of arms through Sudan’s southern corridors reflects more than the collapse of central control—it signals a pan-African insurgent realignment. These smuggling routes are quickly transforming into strategic arteries of destabilization, directly undermining regional peace, displacing vulnerable populations, and fueling hybrid militant economies. Without decisive and coordinated action, this shadow network will reshape the conflict map of central and eastern Africa.
