WASHINGTON, Feb 24 (Reuters) - Four years after Russia's full-scale invasion of Ukraine, U.N. 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.
