A refugee crisis occurs when a large number of people flee their home country due to conflict, persecution, or natural disasters. These individuals, known as refugees, seek safety and protection in other countries. The sudden influx of refugees can strain resources and services in host nations, leading to social and economic challenges. International organizations, such as the United Nations High Commissioner for Refugees (UNHCR), work to provide assistance and support to refugees. They help with shelter, food, and legal protection, aiming to ensure that refugees can rebuild their lives and eventually return home or integrate into new communities.
