New Delhi, Aug 07 (ANI): Uproar was raised among historians and politicians as a textbook in West Bengal that termed freedom fighters as terrorists came to light. A history chapter titled _revolutionary terrorism_ describes the activities of freedom fighters like Shahid Khudiram Bose, Jatindranath Mukherjee and Prafulla Chaki as _extremism and terrorism_. Shiv Sena leader Sanjay Raut said that it should be noticed that who wrote the book and strict action must be taken. SP leader Naresh Agarwal said that West Bengal Chief Minister Mamata Banerjee must intervene and ban such books which spread incorrect knowledge. Meanwhile, historian S Irfan Habib said that calling freedom fighters as terrorists is incorrect and one should understand their cause of fight and look for alternate and suitable terms which do not insult our freedom fighters.
