On 17 August 2005, around 500 bomb explosions occurred at 300 locations in 63 out of the 64 districts of Bangladesh. The bombs were exploded within a half hour period starting from 11:30 am. A terrorist organization, Jama'atul Mujahideen Bangladesh (JMB) claimed responsibility for the bombings. The group, led by Shaykh Abdur Rahman and the elusive Siddiqur Rahman (also known as Bangla Bhai), is alleged to be affiliated with Al Qaeda. Though, this alleged connection has never been proven. Another terrorist group, titled Harkat-Ul Jihad al Islami was also associated with JMB in executing the co-ordinated attack. Following the blast, both groups were banned by the Government of Bangladesh.
The explosion killed 2 people (a child in Savar, near Dhaka, and a Rickshaw-puller in Chapai Nawabganj District).
The main perpetrators of the bombing, Bangla bhai and Shaykh Abdur Rahman, were later captured by Rapid Action Battalion. And along with 4 other militants, were executed by hanging on 30 March 2007.[1]
