UN Human Rights Chief Volker Türk on Friday urged the authorities to conduct a ‘prompt, impartial, thorough, and transparent’ investigation into the attack that led to Sharif Osman Bin Hadi’s death, and to ensure due process and accountability for those responsible.

Türk said he was deeply troubled by the killing of Hadi, a prominent leader of last year’s protests in Bangladesh, who died of his injuries after being shot last week.

Türk called for calm and for everyone to refrain from violence. “Retaliation and revenge will only deepen divisions and undermine the rights of all,” he said.

Several protests erupted at various locations around the country after Hadi’s death was announced on Thursday, six days after he was shot. Some buildings were torched and vandalised, and a number of journalists have reportedly been assaulted.

With the parliamentary elections scheduled for February, Türk said it was vital to ensure an environment in which all individuals can participate safely and peacefully in public life, and freely express different views.

“I urge the authorities to uphold the rights to freedom of expression, peaceful assembly, and security of journalists at this critical time, and prevent further escalation of unrest,” Türk said.

The High Commissioner said his Office stands ready to work with the authorities and all stakeholders to support efforts that uphold human rights and prevent further violence.
