World Bank Group Debars United Aviation Services Limited and Its Owner

WASHINGTON, August 5, 2026—The World Bank Group today announced the 31-month debarments of United Aviation Services Limited (UNASEL), a transportation services company based in Nigeria, and its owner and President, Air Vice Marshal Alkali Mamu, in connection with fraudulent practices under the Enhancing Niger Northeastern Connectivity Project. The project aims to enhance connectivity and road safety along the Zinder-Agadez Road section and improve access to basic socio-economic infrastructure for selected communities in that road section. According to the facts of the case, UNASEL and Mr. Mamu presented false experience documents in a prequalification application to qualify for a contract under the project. This was a fraudulent practice under the World Bank’s sanctions framework. The debarments make UNASEL and Mr. Mamu ineligible to participate in projects and operations financed by Bank Group institutions. The debarments are part of two settlement agreements under which UNASEL and Mr. Mamu admit culpability for the underlying sanctionable practices. Per the Bank Group Sanctioning Guidelines, the settlement agreements provide for a reduced period of debarment in light of UNASEL and Mr. Mamu’s cooperation. As a condition for release from sanction under the terms of the settlement agreements, UNASEL and Mr. Mamu commit to developing and implementing integrity compliance measures that reflect the relevant principles set out in the Bank Group Integrity Compliance Guidelines, and Mr. Mamu further agrees to complete corporate ethics training. UNASEL and Mr. Mamu also commit to continue to fully cooperate with the Bank Group’s Integrity Vice Presidency. The debarments of UNASEL and Mr. Mamu qualify for cross-debarment by other multilateral development banks under the Agreement for Mutual Enforcement of Debarment Decisions that was signed on April 9, 2010.
