International organizations respond to humanitarian crises by coordinating relief efforts, mobilizing resources, and providing essential services like food, medical aid, and shelter. They operate within frameworks established by international law and human rights standards, bringing together governments, NGOs, and local communities to address urgent needs. Organizations such as the United Nations play a crucial role in facilitating negotiations for ceasefires and peace agreements while ensuring that humanitarian principles guide their interventions. Their efforts are vital in fostering stability, rebuilding communities, and addressing the root causes of crises.
