Lithuania's intelligence agency is concerned that migration and terrorism are distracting Western countries from Russia's "aggressive policies" toward its neighbors.

In its annual report Wednesday, the State Security Department said Russia continues to pose a political and military threat to Lithuania, which broke away from the Soviet Union in 1991.

The report said Russia's military would need 24-48 hours to amass enough forces "to start military actions against Baltic states."

The agency said the migration crisis is dangerous because it's hurting the unity of the European Union and "will distract attention of Western countries and organizations from the security situation in Eastern Europe."
