Jagrata Muslim Janata Bangladesh (Awakened Muslim Masses of Bangladesh), also known by the acronym JMJB, is an Islamist extremist organisation based in Bangladesh, especially around the country's north-western region. The Government of Bangladesh has classified JMJB as a terrorist organisation and banned it. It is related to Jamaat-ul-Mujahideen Bangladesh, and is described by Bangladesh Police as an off shot.
Their leaders include its chief Siddikul Islam alias Bangla Bhai, and Shaykh Abdur Rahman. After the Government of Bangladesh proclaimed a large reward for the capture of Bangla Bhai, he was captured by police and Rapid Action Battalion in Mymensingh District on 6 March 2006. JMJB is run by three leaders Muhammad Asadullah Al-Ghalib, Bangla Bhai, and Shaykh Abdur Rahman. Bangla Bhai, and Shaykh Abdur Rahman were executed on 30 March 2007.
The JMJB is extremely critical of the Jamaat-e-Islami Bangladesh, which it deems as heretical due to the latter's participation in the Bangladeshi political establishment and patronisation of secularism and sacrilege of Islamic values and principles. The Group is inspired by the ideology of the Afghan Taliban. They were patronised by some Bangladesh Nationalist Party government members to attack left-wing guerrilla movement by Purbo bangla Communist Party. They wanted to establish sharia law in Bangladesh.
