Ghulam Azam, the Islamist leader who has been accused of masterminding the human-rights violations during the country’s 1971 war against Pakistan, was sentenced Monday to 90 years by the International Crimes Tribunal. Azam, 90, has been called Bangladesh’s Hitler, and many had called for capital punishment. The tribunal showed leniency due to Azam’s advanced age and health complications. “Some kind of justice is done, but we are not happy,” said junior attorney general M.K. Rahman. Azam’s supporters clashed with police throughout Bangladesh, with dozens injured in the capital, Dhaka. The nation’s largest Islamic party, Jamaat, called for a nationwide protest Monday against the verdict.
