organise military training near the Latvian border. The Russian Federation carries out influence measures also against Latvia, thus elements of so-called hybrid threat can be identified also in Latvia. A complex and long-term action must be carried out in order to reduce and prevent these elements. The ever growing confrontation between the Russian Federation and the West, aggressive demonstration of military capacity, and increasing of the capacity in the strategic direction of the West cause tension and uncertainty. Additionally, informative propaganda disorientates the society and decision making. These risk factors require to increase the national security measures in the Republic of Latvia and Baltic region. Significant threats to Europe come from the instability in the Middle East region. These threat sources are linked to destabilisation of separate countries in the region, increase of the number of refugees and asylum seekers, possible trade of weapons of mass destruction, radicalisation of the society of these countries, and increasing threats of terrorism. Threats to the national security caused by international terrorism and its consequences have increased. In recent years, terrorism has developed into a complex and extensive issue that not only challenges the safety and stability of countries, but also is directed against common basic values. ISIL/Da'esh terrorist organisation is considered to cause very significant threat because, due to its actions and methods, the organisation has become a driving force for other organisations, thus establishing new tendencies in so-called global jihad. Significant threat has arisen from so-called foreign fighter phenomenon that includes people with financial problems or due to their ideology travelling to the conflict areas in order to fight for the terrorist organisation. Radicalisation of these people and threats they create after returning to their origin countries, including Europe, are long-term threats that have not been fully identified yet. This requires cooperation on national and international level in order to prevent further expansion of the phenomenon. International economic processes significantly affect the international security environment, specifically ever growing competition between countries, economic integration processes on regional and international level, as well as mutual dependence on import, export, and production process within the control context. The international economic crisis and fallowing economic issues in EU and globally clearly identify the link between economic issues and other security elements.
