The Union of Forces for Democracy and Development–Fundamental (UFDD–F) is one of the rebel groups fighting in the war in Chad.[1] It is led by Abdelwahid Aboud Mackaye.[2] The UFDD-F is essentially an Arab organization, which was formed as a dissident split from the UFDD following tensions and conflicts of interest between Arab militants and Tubu militants who dominated the organization.[3]
