The Jamaat-e-Islami Hind has demanded "stringent action" against those who carried out a string of bomb attacks in Patna killing six people.
Expressing grief over the deaths, Jamaat secretary general Nusrat Ali warned that communal forces might now create an environment of "fear and terror" in Bihar for electoral gains.
Ali urged the Bihar and the central governments to maintain peace ahead of the Lok Sabha election due next year.
