Mufti Hannan was the leader of Harkat-ul Jihad al-Islami Bangladesh (HujiB).
On March 21, the Supreme Court’s Appellate Division released the full text of its verdict confirming the death penalties of Mufti Hannan and two of his aides.
The HujiB militant group was formed in 1992 and claims to have carried out at least 14 attacks, killing more than 100 people in the pursuit of “establishing Shariah law in Bangladesh”.
