Four fugitive militants have been sentenced to 40 years in prison for their involvement in a November bomb attack that killed two judges. The sentences will commence when the four, including Shayek Abdur Rahman, supreme leader of Jamaat-ul-Mujahideen and Siddikul Islam Bangla Bhai, chief of Jagrat Muslim Janata Bangladesh are arrested, court officials said. The judgment was given by a speedy trial court in Barisal, about 300 km (190 miles) south of Dhaka, which tried the four in their absence. The government outlawed the two groups early last year for criminal activities and later blamed them for a wave of countrywide bomb attacks that killed at least 30 people, including the two judges, and wounded 150 since August 2005, Reuters reported. Police have detained around 900 suspects since August but Shayek Rahman and Bangla Bhai are at large.
