“Mullah Omar’s son and brother, both who previously opposed the appointment of Mullah Akhtar Mohammad Mansour to serve as the new leader of the Taliban, have changed their minds and sworn allegiance to Mansour, according to the Taliban. The jihadist group released an Arabic-language statement on Voice of Jihad, its official propaganda website, claiming that Mullah Abdul Manan Akhund, a brother of Mullah Omar, and Mullah Mohammad Yaqoub, Omar’s eldest son, had sworn allegiance to Mansour after meeting with the new Taliban emir. The meeting ‘was attended by a large number of sheikhs and scholars valued and senior Islamic Emirate officials,’ according to the statement.”
