International NGOs play a crucial role in humanitarian crises by providing aid, advocacy, and expertise in conflict zones. They mobilize resources and coordinate relief efforts to address immediate needs such as food, shelter, and medical care. NGOs also advocate for human rights, often operating in politically sensitive environments where local or national governments may be unable or unwilling to act. Their presence can draw international attention to crises, potentially influencing public opinion and policy responses from governments and international organizations, thereby promoting accountability and long-term solutions.
