In late 2004 and early 2005, two professors of Rajshahi University got assassinated within three months: Professor Yunus from the Economics department in December 2004 and Professor Taher from the Geology and Mining department in February 2005. Both murders were suspected to be driven by political motivations. In 2006, the commander of Jama'atul Mujahideen Bangladesh admitted to the RAB interrogators that his operatives carried out the attack on Yunus, as well as the 2004 attack on writer Humayun Azad, the murder of another writer, bomb blasts, and attacks on cinemas.
