Based on many of the international principles such as the International Minimum Standard of Treatment (which is today accepted as a general international principle in the international law in treating the aliens), the states international responsibility for damages to the properties or aliens in their territory, the principle of treatment based on the Human Rights international standard, etc., the host countries are deemed responsible for the damages to the aliens. The current study has sought to respond to the question that what international responsibilities do the host countries have for the damages to the aliens, through the use of the qualitative method and library-based data collecting procedures. The findings indicate that the country in which an alien resides must protect is soul and property in that domain, to the extent which conforms to the International Minimum Standard of Treatment, and in relation to protection of people’s security, soul, and property, the state must treat him as it treats its nationals, and they must be equal before law. In this regard, the host country is responsible for the damages and damages due to action or inaction by the Judiciary, the decisions and measures of the executive power (the state’s organ or agent), and the damages due to the military actions by the rebels or the revolutionaries, etc., and it is bound to compensate the damages.
