UN High Commissioner for Human Rights Volker Türk on Friday expressed deep concern over the killing of Inqilab Moncho Spokesperson Sharif Osman Bin Hadi and called for calm amid rising tensions.

“Retaliation and revenge will only deepen divisions and undermine the rights of all,” he said in a statement.

Türk also urged the authorities to conduct a prompt, impartial, thorough and transparent investigation into the attack that led to Hadi’s death, and to ensure due process and accountability for those responsible.

Protests erupted at various locations across 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 election scheduled for February, the UN rights chief 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,” he said.

Türk said his office stands ready to work with the authorities and all stakeholders to support efforts that uphold human rights and prevent further violence.
