In the wake of the terrorist attacks in Paris on November 13, the U.S. Embassy in Riga reminds U.S. citizens in Latvia to review the Worldwide Caution, which provides information on the continuing threat of terrorist actions and violence against U.S. citizens and interests throughout the world, including Europe. Recent terrorist attacks, whether by those affiliated with terrorist entities, copycats, or individual perpetrators, serve as a reminder that U.S. citizens need to maintain a high level of vigilance and take appropriate steps to increase their security awareness.
