The paper defines the terrorist acts as a combination of factors that have a negative impact on the economic, social and natural environment of society. The UNWTO is a hub for these joint activities to organize tourism security. The distinguishing and novel feature of the organization is that, whilst most organizations provide international security for people permanently residing in a certain territory, the UNWTO interacts exclusively with relocated persons. The work undertaken by the UNWTO specifies that the threat in the tourism industry has a character of mutual exclusion in the aspect of presenting political claims as the causes of terrorism and reducing economic and social indicators as consequences of the activities of terrorist groups.
