Sudan chemical weapons allegations have prompted the TASIS-backed administration to invite United Nations investigators into territories under its control, calling for an independent examination of claims involving Sudan’s regular armed forces.
The invitation follows the UN Human Rights Council’s decision to extend the mandate of its Independent International Fact-Finding Mission for Sudan for another year.
In a statement, Information Minister and government spokesperson Khalid Ahmed Danaa said the administration was prepared to cooperate with investigators and provide access to relevant locations.
Sudan’s military-aligned authorities have denied allegations of chemical weapons use.
TASIS seeks probe into Sudan chemical weapons allegations
The TASIS-backed administration said UN investigators would be permitted to inspect suspected attack sites, collect evidence and interview witnesses in areas under its control.
Danaa said officials were willing to facilitate interviews with victims and survivors without interference.
The administration also called for scientific and forensic examinations to determine whether chemical agents had been used during the conflict.
It urged investigators to examine alleged attacks on civilians and civilian infrastructure, alongside other reported violations.
However, the allegations remain disputed, and the invitation does not establish responsibility for any alleged incident.
UN extends Sudan fact-finding mission
The UN Human Rights Council voted on October 5 to extend the mandate of its Independent International Fact-Finding Mission for Sudan.
The resolution received 28 votes in favour, 10 against and nine abstentions.
The mission investigates alleged violations of international human rights and humanitarian law committed during Sudan’s conflict.
Its responsibilities include documenting abuses, preserving evidence and identifying individuals or groups potentially responsible for serious violations.
The renewed mandate allows investigators to continue examining alleged violations and reporting their findings to international bodies.
The TASIS-backed administration welcomed the decision and called for direct communication with UN officials to arrange possible visits.
There has been no confirmation that UN investigators have accepted the invitation or entered TASIS-controlled territory.
US previously raised chemical weapons concerns
The latest appeal follows earlier allegations concerning chemical weapons use in Sudan.
In April 2025, the United States determined that Sudan’s government had used chemical weapons in violation of international obligations.
Washington subsequently introduced sanctions and additional restrictions linked to that determination.
Sudan’s military-aligned authorities rejected the accusations and disputed their basis.
The US determination represents Washington’s official position. It does not replace an independent forensic investigation into specific alleged incidents.
Establishing whether chemical weapons were used, where they were deployed and who was responsible would require reliable evidence and independent examination.
Accountability remains a challenge in Sudan
The question of independent access remains important as Sudan’s conflict continues.
The Port Sudan-based authorities have previously opposed the UN fact-finding mission and faced criticism over restrictions on cooperation with investigators.
The TASIS-backed administration says it is prepared to allow investigators into areas under its control.
However, any credible investigation would need to operate independently and examine allegations involving all parties to the conflict, including the Rapid Support Forces (RSF), Sudan’s regular armed forces and allied groups.
Investigators would also need access to witnesses, protection from interference and reliable forensic evidence.
The latest invitation could provide an opportunity for further investigation if the UN mission secures independent access.
For now, the allegations remain contested, and responsibility for specific alleged incidents has not been established through the proposed investigation.
