As top leaders of banned militant outfit Harkat-ul-Jihad-al Islami Bangladesh (HuJI-B) are either hanged or behind bars, its operatives are now joining another outfit Ansar al Islam responsible for killing bloggers, writers and free thinkers, said Mozammel Haque, Commanding Officer (CO) of Rapid Action Battalion-4 (RAB-4), at a press conference at RAB media centre on October 21, reports The Daily Star. He said this following arrest of four Ansar al Islam men - Mufti Saiful Islam (34), Salim Mia (30), Zunayed (37) and Ahmed Sohayel (21) from Dhaka city on October 20. Of them, Saiful and Zunayed were once affiliated with HuJI-B but are now holding important posts in Ansar al Islam, Mozammel said. The arrestees in preliminary interrogation said they hate the existing Government system and want to establish an Islamic law-based system through so-called Jihad, he said.
