At least 18 leaders and activists of Islami Andolan Bangladesh lost their lives in the anti-discrimination student movement in July and August.
Additionally, more than a thousand have been injured, with over 150 seriously injured and receiving treatment in various hospitals.
The information was revealed by party's Naib-e-Amir Mufti Syed Muhammad Faizul Karim.
He said: "Our student community has initiated the struggle to overthrow the most brutal and barbaric Awami League misrule in the history of the country. Their immense courage, sacrifice, and wise leadership have made us proud. Islami Andolan Bangladesh has been involved in this movement from the very beginning."
Faizul Karim made these remarks at a press conference held at Nayapaltan in the capital on Tuesday.
He further said: "On July 19, we announced that the resignation of the government is the only solution. From the very beginning, leaders and activists of Islami Andolan have participated in this movement in various capacities and forms. We take pride in the role we have played in a great revolution. Many of our brothers have given their lives and many have been injured."
