Jihadister har satt igang en voldelig kamp for å innføre sharia. De har valgt seg ut jurister og journalister, som symboler på et verdslig styresett.
The group police suspect is Jamaat-ul-Mujahideen, which wants to establish Islamic law in Bangladesh. Most laws in Bangladesh are secular, based on British legal code.

Lawyers and judges have received threatening letters from the group in the past few weeks.
Earlier this month, two judges were killed in a bomb attack as they travelled to court in southern Bangladesh.
