Afghan intelligence officials have described the Dadullah Front as affiliated with the Taliban. Taliban spokesmen denied any relationship with the Front, and claimed that the group was a creation of the Afghan intelligence agency, the National Directorate of Intelligence. Following the August 2015 announcement that Akhtar Mansour had succeeded the deceased Mullah Omar as leader of the Taliban, Dadullah refused to support him, leading to months of clashes between their forces in Zabul Province, resulting in the killing of Dadullah and many of his supporters in November 2015. In August 2016, the Dadullah Front announced Dadullah's nephew Mullah Emdadullah Mansoor as its new leader, and threatened to take revenge on the Taliban. The group has been linked to another Taliban splinter group, Fidai Mahaz, but the groups are believed to be separate.
