United Nations Secretary-General Antonio Guterres met with Iranian President Ebrahim Raisi in New York on Thursday and raised human rights issues, a UN spokesman said on Friday.
The UN is concerned "about reports of peaceful protests being met with excessive use of force leading to dozens of deaths and injuries," spokesman Stephane Dujarric told reporters.
"We call on the security forces to refrain from using unnecessary or disproportionate force and appeal to all to exercise restraint to avoid further escalation," he said.
