"All this work is essential, but it doesn’t address the root cause of all this human suffering: the war itself. This war must end, and peace must established in line the charter of the United Nations and international law. Many leaders have made many good efforts to stop the fighting, though these efforts, so far, have not succeeded. I am here to say to you, Mr. President, and to the people of Ukraine: We will not give up. As we keep pushing for a full-scale ceasefire, we will also keep striving for immediate practical steps to save lives and reduce human suffering. Effective humanitarian corridors. Local cessations of hostilities. Safe passage for civilian and supply routes. Today, the people of Mariupol are in desperate need for just such an approach. Mariupol is a crisis within a crisis. Thousands of civilians need life-saving assistance. Many are elderly, in need of medical care or have limited mobility. They need an escape route out of the apocalypse. During my visit to Moscow, President Putin agreed, in principle, to the involvement of the United Nations and the International Committee of the Red Cross in the evacuation of civilians from the Azovstal plant in Mariupol. Today, President Zelenskyy and I had the opportunity to address this issue. As we speak, there are in intense discussions to move forward on this proposal to make it a reality."
