In response to today's killing of Rajshahi University Professor Rezaul Karim Siddique, Amnesty International said the attackers must be brought to account.

Champa Patel, Amnesty International’s South Asia Director, said, "The vicious killing of Rezaul Karim Siddiquee is inexcusable and those responsible must be held to account.”

“This attack sadly fits the gruesome pattern established by Islamist extremist groups in Bangladesh who are targeting secular activists and writers.”

The authorities must do more to put an end to these killings, Patel said.

“Not a single person has been brought to justice for the attacks over the past year," she pointed out in her statement.

Earlier in the morning, Professor AFM Rezaul Karim Siddiquee of Rajshahi University was killed by miscreants in the city's Shalbagan area.

Witnesses said a group of miscreants swooped on Rezaul Karim, 58, a professor of English Department of the university, around 7:30am near his residence and stabbed him indiscriminately, leaving him dead on the spot.
