NEW YORK: The UN high commissioner for human rights on Tuesday urged Iran to immediately halt violence and repression against peaceful protesters, restore full access to the internet and telecommunications, and ensure accountability for serious human rights violations.

Volker Turk said he is horrified by reports of mounting violence by security forces against demonstrators across Iran, with hundreds reported killed and thousands arrested since protests erupted earlier this month.

“The killing of peaceful demonstrators must stop, and the labeling of protesters as ‘terrorists’ to justify violence against them is unacceptable,” he added.

It is “extremely worrying” to see public statements by Iranian judicial officials indicating the possible use of the death penalty against protesters through expedited judicial proceedings, Turk said.

He added that the protests echo mass demonstrations seen in 2022, with broad segments of the population demanding fundamental changes in governance.

He also criticized authorities for responding with what he described as brutal force to suppress legitimate demands.

“This cycle of horrific violence cannot continue,” he said, adding that all killings, violence against protesters and other alleged abuses must be investigated in line with international human rights standards, and those responsible held to account.

Turk also expressed alarm over reports that hospitals are overwhelmed by casualties, including children, and said nationwide internet and telecommunications shutdowns have hampered verification of events and obstructed independent human rights monitoring.

Iranian authorities imposed a nationwide internet shutdown on Jan. 8, which the UN said has disrupted freedom of expression, access to information, and emergency and lifesaving services. There are also reports that members of Iran’s security forces have been killed during the unrest.

Iranians have the right to demonstrate peacefully, Turk said, adding that their grievances must be heard and addressed, and “not instrumentalized by anyone.”
