UN Secretary-General Antonio Guterres condemned the Russian invasion of Ukraine again today, during the two-day meeting of the General Assembly of the Organization on the occasion of the completion of one year since the start of the war.

“The (Russian) invasion is an insult to our collective conscience,” Guterres said, calling the anniversary a “sad milestone” for the people of Ukraine and the entire international community.

Referring to Moscow’s nuclear threats, the UN secretary-general said: “We have heard indirect threats to use nuclear weapons. The so-called use of non-strategic (or tactical) nuclear weapons is absolutely unacceptable. It is time to move away from the brink,” Guterres stressed.

He reiterated his fears of an escalation of the conflict and added that the longer hostilities continue, the more difficult it will become to reach a peace agreement to end the war.

A sustainable peace must be based on the principles of the Charter of the United Nations and international law, the UN secretary-general underlined.
