Refugees in a broad sense refer to people who are homeless, displaced and need to leave their original places because of natural and man-made disasters.

According to article 1 of the Convention relating to the Status of Refugees adopted by the United Nations in 195 1, a refugee refers to a person who is unwilling or unable to return to his country of origin or be protected by it because of his race, religion, nationality, membership of a special social group or political opinions, and who has good reasons to fear persecution.

The term refugee also applies to anyone who is forced to leave his habitual residence and seek refuge outside his country of residence or nationality because his country of residence or nationality has been invaded, occupied, ruled by foreign countries in part or in whole or because of events that seriously endanger public order.
