UN Marks International Day of Peace 2026 With 'Invest in Peace' Call as Guterres Warns Dialogue Is 'Faltering'

September 21, 2026 — The United Nations observed the International Day of Peace under the theme 'Invest in Peace — For Everyone, Everywhere, Every Day.' In his message, Secretary-General António Guterres said the world faces rising conflict, violence and division causing suffering for millions, that dialogue is 'faltering,' solutions are 'elusive' and global solidarity is 'missing in action,' while crediting volunteers, civil society and peacekeepers with bridging divides from the ground up. The observance came a day ahead of the UN General Assembly's high-level debate, where Gaza, Ukraine and Sudan dominated the agenda.
