A total of 6.3 million Afghan refugees were hosted in Iran and Pakistan by 1990. Afghanistan was the largest refugee-producing country in the world, a title held for 32 years until 2013. Afghans are currently the second largest refugee group after Syrian refugees. The majority of Afghan refugees (95%) are located in Iran and Pakistan. Some countries that were part of the International Security Assistance Force (ISAF) took in small number of Afghans that worked with their respective forces. Ethnic minorities, like Afghan Sikhs and Hindus, often fled to India.
