WASHINGTON: Four years ‌after Russia’s full-scale invasion of Ukraine, UN Secretary General Antonio Guterres said the war there remained “as a ​stain on our collective conscience” and reiterated calls for an immediate ceasefire. In remarks for a session of the United Nations Security Council to mark the fourth anniversary of Russia’s invasion, Guterres commended the efforts of the United States and others to end ‌the war, but ‌said concrete measures were ​needed ‌to ⁠de-escalate ​and create space ⁠for diplomacy.

Referring to Russia’s invasion, Guterres said: “We have witnessed the cascading consequences of this blatant violation of international law.”

He said more than 15,000 civilians had been killed in Ukraine since the start of the war ⁠and over 41,000 hurt. Among those killed ‌or hurt were ‌3,200 children.

Guterres’ remarks were ​read on his ‌behalf by Rosemary DiCarlo, the UN under-secretary-general for ‌peacebuilding.

Guterres warned that the fighting posed direct risks to the safe and secure operation of Ukraine’s nuclear sites, and added: “This unconscionable game of ‌nuclear roulette must cease immediately.”
