U.S. seeks broader UN arms embargo on Sudan

The United States (U.S.) has launched a major diplomatic initiative at the United Nations (UN) by proposing the expansion of the existing arms embargo on Sudan’s Darfur region to cover the entire country. The proposal comes as Sudan’s civil war enters its fourth year, with escalating violence, widespread displacement, and growing concerns that the conflict could further destabilize the Horn of Africa.

However, the proposal faces significant political hurdles, most notably opposition from Russia, which has warned against measures that could undermine the Sudanese Armed Forces (SAF).

A new push to expand the arms embargo

Addressing the UN Security Council, U.S. Senior Advisor for Arab and African Affairs Massad Boulos called on member states to adopt a stronger sanctions regime aimed at reducing the military capabilities of all parties to the conflict. The existing UN arms embargo, imposed exclusively on Darfur in 2005, is due to expire on 12 September 2026, unless renewed or amended.

Washington’s proposal seeks not only to extend the embargo geographically to encompass all Sudanese territory but also to modernize it by including unmanned aerial vehicles (UAVs) and related military technologies. The U.S. further proposed increasing the number of experts responsible for monitoring violations and improving coordination between sanctions monitoring teams tasked with enforcing asset freezes, travel bans, and arms restrictions already imposed on individuals linked to the conflict.

According to Boulos, external military and financial support continues to fuel the fighting and risks drawing neighboring countries deeper into the crisis. He argued that stronger international action is necessary to prevent the conflict from expanding beyond Sudan’s borders.

A conflict increasingly defined by advanced weaponry

Sudan’s war, which erupted in April 2023 following a power struggle between the SAF, led by General Abdel Fattah al-Burhan, and the Rapid Support Forces (RSF), commanded by Mohamed Hamdan Dagalo (Hemedti), has evolved into one of the world’s most devastating humanitarian crises.

While conventional ground battles continue across several regions, the conflict has increasingly been characterized by the widespread use of armed drones and other sophisticated military technologies. According to UN officials, drone attacks launched by both sides have struck civilian infrastructure, including schools, markets, fuel stations, and water facilities, significantly increasing civilian casualties.

The UN estimates that more than 1,100 civilians were killed in drone attacks during the first half of 2026 alone. Although the exact overall death toll remains uncertain, UN officials believe the number of fatalities since the war began is likely to be in the hundreds of thousands, while more than 14 million people have been displaced from their homes.

Darfur remains the epicenter of humanitarian suffering

Despite the conflict spreading across much of Sudan, Darfur continues to experience some of its worst violence. Comparable in size to France, the western region has witnessed repeated attacks on displacement camps, widespread destruction, and recurring ethnically motivated massacres.

UN experts have warned that atrocities committed during recent offensives in Darfur bear disturbing similarities to the genocidal violence that devastated the region nearly 20 years ago. The RSF currently controls large parts of Darfur and areas in southern Sudan, while the SAF maintains control over much of the country’s central and eastern regions.

Observers acknowledge that the existing Darfur-specific embargo has had limited success in preventing weapons from reaching armed groups. Numerous investigations have documented repeated violations of the sanctions regime, raising questions about its effectiveness in the absence of stronger enforcement mechanisms.

Political divisions at the Security Council

Any attempt to expand the embargo requires approval by the UN Security Council, where geopolitical divisions threaten to block the initiative. Russia, a permanent member with veto power, has expressed strong reservations, arguing that additional restrictions could weaken Sudan’s national army and reduce its ability to combat the RSF.

China has also expressed caution regarding broader sanctions, stressing that diplomatic efforts should remain the primary avenue for resolving the conflict.

Sudan’s Permanent Representative to the UN similarly rejected the U.S. proposal, calling instead for a purely technical renewal of the existing Darfur embargo without expanding its scope. He argued that while Sudan suffers from the illicit flow of weapons, additional sanctions would ultimately weaken the government’s ability to protect civilians.

The debate reflects broader disagreements within the international community over whether stricter sanctions would help contain the conflict or instead further complicate efforts to restore stability.

Burhan rejects international pressure

Inside Sudan, General Abdel Fattah al-Burhan dismissed speculation regarding possible international sanctions or broader restrictions on his country’s military operations.

Speaking during the graduation ceremony of a new class of police officers in Khartoum, Burhan insisted that discussions of sanctions or even potential no-fly measures would neither weaken the SAF nor alter its military objectives. He reaffirmed the army’s commitment to continuing what it describes as the “Battle of Dignity” until all territory controlled by the RSF is recaptured.

Burhan also criticized Sudanese political groups operating abroad that have opposed his calls for an internal national dialogue. In particular, he attacked members of the civilian coalition “Sumoud,” led by former Prime Minister (PM) Abdalla Hamdok, accusing them of supporting foreign pressure against Sudan and insisting that they no longer represent the aspirations of the Sudanese people.

Opposition groups, however, have rejected Burhan’s proposed dialogue, arguing that it lacks credibility and risks institutionalizing the country’s de facto territorial divisions rather than creating a genuine path toward peace.

External support continues to fuel the war

International organizations continue to warn that both warring factions receive military assistance from external actors despite existing sanctions. Human rights organizations have documented the presence of weapons originating from several countries, while reports suggest that drones and other advanced systems have significantly altered the battlefield.

UN officials argue that the continued availability of sophisticated weaponry demonstrates that sanctions enforcement remains inadequate. Washington believes that expanding the embargo nationwide, strengthening monitoring mechanisms, and specifically targeting drone technologies could help reduce the flow of weapons sustaining the conflict.
