the national security of the Republic of Latvia. This means that the Republic of Latvia and other member states of EU and NATO have to send their forces to participate in the international peace keeping missions in order to support other countries in their efforts to control the situation in their territories; at the same time, these actions prevent terrorist ideas and trends from spreading outside the said regions. International cooperation plays a significant role in prevention of various threats caused by the international terrorism, and is considered as one of the most important element in the counter-terrorism measures. In the context of counter-terrorism, the Republic of Latvia has to actively contribute to the activities carried out by NATO and EU in order to reduce and timely prevent terrorism threats directed towards the member states of EU and their population. At the same time, the state security authorities must continue to develop and improve the information exchange with special services of other countries. Cooperation of the State, Municipalities, and Judicial Authorities in the Area of Counter-terrorism Within the framework of the national counter-terrorism system, the state security authorities and other institutions involved in the counter-terrorism measures must ensure more efficient cooperation in order to provide a timely information exchange in regard to terrorist threats. In the framework of the counter-terrorism measures, a regional cooperation must be established to develop a unified understanding about the counter-terrorism measures and actions that have to be taken in the case of terrorism threats. In addition to cooperation with other institutions, the Security Police (the major coordinator of the counter-terrorism measures) must ensure that the current plans and procedures will be reviewed, as well as they will be executed regarding the specific security situation in the relevant region. Security of the Terrorism Risk Objects The state security authorities must continue to carry out activities developed for improvement of physical security level of the terrorism risk objects (critical infrastructure and crowded places), as well as, if necessary, must entirely review the critical infrastructure. It is necessary to ensure coordination of development of the documents regulating security measures for the critical infrastructure objects, as well as control of the implementation efficiency. 4.8.
