United Nations Secretary-General Antonio Guterres Monday slammed as "totally unacceptable" the crackdown by Iran’s authorities on protests.

In a wide-ranging news conference to close out 2022, Guterres also said that he "will not relent in the pursuit of peace in Ukraine in line with international law and the United Nations Charter." A key principle of the founding UN Charter is respect for sovereignty and territorial integrity.

He is "not optimistic" about the possibility of effective Ukraine and Russia peace talks in the immediate future and believes the military confrontation will go on but added that he "strongly hopes" there can be an end to the war in 2023.

The General Secretary added on Iran that "we are witnessing massive violations of human rights that we strongly condemn."

He also said there is a risk of losing the 2015 Iran nuclear deal known as JCPOA. Long negotiations since April 2021 between the West and Iran came to an impasse in September and since, the United States and European powers say they are focused on the human rights situation in Iran and not on the JCPOA.

The UN Human Rights Council has slammed Iran’s violations and decided to launch an investigation into killings and large-scale imprisonments. Iran was also expelled last week from the UN Commission on the Status of Women, in a drive led by the US.
